Best time to go fishing at sea, these can be determined based on the knowledge about weather. So, option A is correct.
The weather of a location refers to the average conditions of the atmosphere there in relation to variables like humidity, temperature, wind speed, rainfall, etc. Cloudy, sunny, wet, stormy, or clear weather are all possible.
The state of the atmosphere at a certain location and time is known as the weather. The weather fluctuates every day depending on the amount of sunshine, heat, clouds, wind, and rain. Weather is primarily influenced by the seasons and climate.
There are six basic factors that make up the weather. They are heat, pressure in the atmosphere, the development of clouds, wind, humidity, and rain. Any one of these factors might alter slightly to produce a distinct weather pattern.
Thus, option A is correct.

Answer:
the answer is A :)
2. Plasmas have a net negative charge.
3. The number of protons in an element is always equal to the number of neutrons.
4. Solids have a fixed mass, volume, and shape.
Answer: Solids have a fixed mass, volume, and shape.
Explanation: Solids are the substances which have fixed shape, fixed volume and mass due to its close packed structure.
Dalton explained that all the elements are made up of small indivisible particle known as Atoms but after some time this was proved wrong as atoms is not indivisble, it conatins sub atomic particle like electrons, protons, neutrons etc.
Plasmas are considered as the fourth state of matter which contains equal quantity of positive ions and negative electrons.
The number of protons are equal to the number of electrons. The sum of number of protons and neutrons make the atomic mass quantity.
Chlorine
Uranium
Ammonia
Among the substances listed, ammonia (NH3) is a compound. The option D (ammonia) is the correct option.
Compounds can have various physical forms, such as solids, liquids, or gases, depending on the specific elements and the nature of their chemical bonds. They can also exhibit a wide range of chemical and physical properties, such as melting point, boiling point, density, solubility, and reactivity.
Chemical formulas are used to represent compound substances, indicating the types and numbers of atoms present in a molecule of the compound. For example, the chemical formula for water is H2O, representing two hydrogen (H) atoms bonded to one oxygen (O) atom. Ammonia is composed of nitrogen (N) and hydrogen (H) atoms bonded together. Carbon (C), chlorine (Cl), and uranium (U) are elements rather than compounds.
Therefore, Ammonia which is option D is the correct option.
