Question

Assertion (A): The specificity of characters decreases from family to genus.​

Reason (R): The species is a lower-level taxonomic unit than the genus.​

Directions: Choose the correct option:​

• A. Both assertion(A) and reason(R) are true and reason(R) is the correct explanation for assertion(A). ​
• B. Assertion(A) is false and reason(R) is true.​
• C. Assertion(A) is true and reason(R) is false.​
• D. Both assertion(A) and reason(R) are true, but reason(R) is not the correct explanation for assertion.​

Answer 1

The correct option is B Assertion(A) is false and reason(R) is true.​

Correct answer: (d) Assertion(A) is false and reason(R) is true.​

​

• The different taxonomic units are arranged in the increasing order of specificity of characters of the organisms .​

• Species is the lowest taxonomic unit in the hierarchy.​

• Therefore, it is the level with greatest specificity.​

• Genus which is the next higher taxonomic unit has lesser specificity than species.​

• Hence the correct option is (d).​
