Answer: The correct answer is-
A. The air contains 50 percent of the moisture it can hold before precipitation occurs.
Humidity can be described as the presence of gaseous state of water (that is water vapor) in the atmosphere or air.
It indicates the chances of occurance of precipitation or fog in the weather.
50% humidity represents the relative humidity, indicating that air is 50% saturated with moisture, which could be held by air before precipitation occurs .
50% humidity indicates that before precipitation the air withholds 50% moisture and it is known as relative humidity.
Further Explanation:
The amount of moisture the air contains is defined by humidity. A particular amount of water vapor is present in the air which depends on the temperature of the air. The warmer air contains holds more water within it. The relative humidity is defined as the content of water vapor found in the air in relation to the amount it can actually hold. When the relative humidity is low, it implies that the air can comparatively withhold more moisture at that particular temperature and this makes the air dry.
For example, it is estimated that a cubic meter of air is able to hold 18grams of water as a maximum value at 20 degrees C. Similarly, at 25 degrees C, 22 grams of water can be held by the air. Therefore, if 22 grams of water is contained in a cubic meter of air at 25 degrees C, then there is 100% relative humidity. But if the same amount of air holds 11 grams of water, the relative humidity is said to be 50%.
The relative humidity plays a major role in maintaining our level of comfort. A 100% relative humidity means that there will be no evaporation of water and the moisture has fully saturated the air. For cooling, the body requires to evaporate the moisture from the skin. A low relative humidity enables the body to release moisture and make the body cooler. At 100% relative humidity, the body feels much hotter as compared to the actual temperature. This is because the body does not sweat to evaporate due to high humidity.

Lake Victoria will shrink and disappear as all of the plates converge.
The African plate will grow larger as all of the plates converge.
Water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area.
The Indian Ocean will shrink and disappear as the Rift Zone gets larger.
The things that you will predict will eventually happen at the East African Rift Zone are the Water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area. Thus, the correct option for this question is C.
Tectonic plates are the types of crustal plates that are gigantic pieces of the Earth's crust and uppermost mantle. A crustal plate may be defined as a type of large block or tabular section of the lithosphere that significantly reacts to tectonic forces as a unit and moves as such.
The movement of the crustal plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Due to this, the water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area.
Therefore, the correct option for this question is C.
