Q. Assertion (A) Hierarchical system of classification is useful to reduce volume's description in a catalogue of organisms.
Reason (R) Characters of a larger category (like division) are not repeated for smaller/ lower categories (family and order).

The Living World

Solution:

Both Assertion and Reason are true and Reason is the correct explanation of Assertion. Hierarchical system of classification helps to reduce description of volume in catalogue of plants and animals. This is because characters for higher categories are not repeated for lower categories. It can be illustrated by an example like Cannis familiaris is common dog, belong to family-Canidae. Genus-Cannis are applied to wolf, jackal of same family.
