Solution
The correct option is B Ethylene
The plant hormone ethylene is growth inhibitor and is released in plant organs that are to undergo ripening or senescence. Ethylene triggers climacteric ripening of the fruit and induces insensitivity of senescent organs to auxins due to which the nutrients are channelized to other growing parts of the plant resulting in withering away of the plant part.So, the correct answer is 'Ethylene'
