Assertion: Ethylene cause climacteric ripening of fruits.
Reason : Climacteric fruits show a rise in respiration at the time of ripening.

Options

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

Answer

B

Explanation

(b) In most fruits the rate of respiration will undergo a sharp rise and then fall near the end of ripening. The climacteric acts as a triggerr that sets inm progress those change that rapidly transform the furit from an umripe to a ripe condition. Finally, application of ethylene ton unripe furit will bring on a premature climacteric and accelerate ripening.
