Correct answer

C. They cause them to elongate and improve shape

Step-by-step solution

All GAs are acidic. They produce a wide range of physiological responses in the plants. Their ability to cause an increase in length of axis is used to increase the length of grapes stalks. Gibberellins, cause fruits like apple to elongate and improve its shape. Spraying juvenile conifers with GAs hastens the maturity period, thus leading to early seed production.
