Assertion-Reason relation

• In lily flowers, sepals (calyx) and petals (corolla) do not show any distinction and are fused together to form a perianth. They show epiphyllous condition as the androecium is attached to the perianth. Hence, the statement given in the assertion is correct.
• In lily flowers, the androecium (whorl of stamens) is fused with the perianth. Hence, the statement given in the reason is correct and it justifies the assertion.

Final answer: a. If both assertion and reason are true and the reason is the correct explanation of the assertion.
