C. Gibberellin	III. Helps in nutrient mobilisation
D. Cytokinin	IV. Promotes bolting in beet, cabbage etc

Choose the correct answer from the options given below:

• A. A-II, B-III, C-IV, D-I
• B. A-III, B-II, C-I, D-IV
• C. A-II, B-I, C-IV, D-III
• D. A-II, B-I, C-III, D-IV

Answer 1

The Correct Option is C

The question involves matching a list of plant hormones (List-I) with their corresponding functions (List-II). Let's solve it step-by-step:

1. Abscisic Acid: Abscisic acid is known for its role in inhibiting growth and promoting dormancy. Specifically, it helps seeds withstand desiccation by inducing dormancy, allowing them to survive adverse conditions. Accordingly, it matches with "II. Helps seeds to withstand desiccation."
2. Ethylene: Ethylene is a hormone responsible for various functions, including fruit ripening and promoting the formation of female flowers in certain plants like cucumber. Thus, it matches with "I. Promotes female flowers in cucumber."
3. Gibberellin: This hormone is well-known for promoting cell elongation and increasing the length of stems. It plays a crucial role in bolting, which is the rapid elongation of a floral stalk in plants like beet and cabbage. Therefore, it matches with "IV. Promotes bolting in beet, cabbage etc."
4. Cytokinin: Cytokinin is involved in promoting cell division and growth, often working in coordination with auxins. It is essential for nutrient mobilisation and therefore matches with "III. Helps in nutrient mobilisation."

Based on the analysis above, the correct matching is: A-II, B-I, C-IV, D-III.
