Question

Assertion : Thorns and tendrils of Bougainvillea and Cucurbita represent homology
Reason : Homologous organs have similar functions but are different in their structural details and origin

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false
