Question

Assertion: Homologous structures are a result of divergent evolution.
Reason: Eyes of an octopus and humans are both analogous structures.

• A. Both the assertion and reason are true and the reason is a correct explanation of the assertion
• B. Both assertion and reason are true but the reason is not the correct explanation of the assertion
• C. Assertion is true but the reason is false
• D. Both assertion and reason are false

Answer 1

The correct option is B Both assertion and reason are true but the reason is not the correct explanation of the assertion

Homologous structures are the result of divergent evolution that occurs when the same structure develops along different directions due to adaptations to different needs. They indicate common ancestry.

The eyes of an octopus and humans are analogous structures which evolved when similar evolutionary pressure compelled the organisms to develop similar adaptive features in different groups of organisms, yet perform the same function. Thus both assertion and reason are true but the reason is not the correct explanation of the assertion.
