As per the modern classificationsystem, the class, order, genus, species is arranged from least specific to most specific one. The correct option is C.
What is classification system?
The term classification can refer to one or more of the following: the process of classifying the resulting set of classes the classification of elements into predefined classes Classifying, in its broadestsense, is a fundamental concept and a component of almost all activities.
In 1956, Herbert FaulknerCopeland (1902-1968) proposed the four kingdom classification.
Monera, Protista, Plantae, and Animalia were the four kingdoms. He classified unicellular organisms into two groups: the Monera kingdom and the Protista kingdom.
The classificationsystem provides a wealth of information about organism characteristics. Using scientific names as a shorthand method of describing a plant or animal can thus be beneficial.
Thus, the correct option is C.

Answer:
100 percent
Explanation:
Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth the relative humidity very rarely falls below 30 percent.
