Identify the correct sentences regarding the role of physiological responses of phytohormones:
I. Ethylene initiates sprouting of potato tubers
II. Gibberellins promote senescence
III. Auxins promote flowering in pineapple
IV, Abscisic acid inhibits seed germination
I. Ethylene initiates sprouting of potato tubers
II. Gibberellins promote senescence
III. Auxins promote flowering in pineapple
IV, Abscisic acid inhibits seed germination
Show Hint
- Gibberellins → Stimulate seed germination (not senescence).
- Abscisic acid → Inhibits seed germination (stress hormone).
- II, III, and IV
- I, III, and IV
- I, II, and IV
- I, II, and III
The Correct Option is B
Solution and Explanation
- Ethylene initiates sprouting of potato tubers.
- Gibberellins promote seed germination, not senescence.
- Auxins promote flowering in pineapple.
- Abscisic acid (ABA) inhibits seed germination.
Step 2: Identifying the Correct Statement
The correct statements are I, III, and IV.

Given the vectors:
\[ \mathbf{a} = \mathbf{i} + 2\mathbf{j} + \mathbf{k} \]
\[ \mathbf{b} = 3(\mathbf{i} - \mathbf{j} + \mathbf{k}) = 3\mathbf{i} - 3\mathbf{j} + 3\mathbf{k} \]
where
\[ \mathbf{a} \times \mathbf{c} = \mathbf{b} \]
\[ \mathbf{a} \cdot \mathbf{x} = 3 \]
Find:
\[ \mathbf{a} \cdot (\mathbf{x} \times \mathbf{b} - \mathbf{c}) \]
