Step 1: Understanding the Concept:
This question tests knowledge of vegetable classification based on life cycle, sexuality, and pollination.
Step 2: Detailed Explanation:
Carrot (B):
- Biennial: Completes life cycle in two years (vegetative growth in first year, flowering in second year).
- Hermaphrodite: Both male and female parts in the same flower.
- Wind pollinated: Cross-pollination by wind.
Characteristics of other vegetables:
- Spinach (A): Annual, dioecious, wind pollinated.
- Sweet corn (C): Annual, monoecious, wind pollinated.
- Beet root (D): Biennial, hermaphrodite but insect pollinated (not wind).
Thus, carrot is the vegetable that is biennial, hermaphrodite, and wind pollinated.
Step 3: Final Answer:
Thus, carrot is biennial, hermaphrodite, and wind pollinated, which corresponds to option (B).
