14. B. I, II, and IV only II. Plants reach maturity faster than ones grown from seeds: This is true. Vegetative propagation bypasses the seedling stage, leading to quicker maturity.IV. Same good agricultural traits such as taste and yields will be maintained: This is a key advantage. Offspring are genetically identical to the parent plant, preserving desirable traits. Statement I is incorrect; not all plants produced through vegetative propagation are disease-resistant. Statement III is also incorrect; the lack of genetic diversity increases the risk of the entire population being wiped out by a single disease. 15. A. Yes, because the onion plants were genetically identical. Since the farmer grew only one type of onion, all the plants are clones and genetically identical. This means they share the same vulnerabilities to diseases. If one plant is susceptible, they all are.
