II. Chamaephytes B. Buds completely hidden in the soil
III. Crytophytes C. Buds naked or covered with scale
IV. Therophytes D. Seasonal plants completing their life cycle in a single favourable season

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

Answer 1

The correct option is B I - C, II - A, III - B, IV - D

The Raunkir system are based on the place of the plant's growth-point (bud) during seasons with adverse conditions:
Phanerophytes: Fairly above the ground 25cm or more, projecting into the air on stems (e.g., trees and shrubs)
Chamaephytes: Buds closer to the ground (e.g., bilberry and periwinkle)
Crytophytes: Buds below ground or under water (e.g., rhizome, bulb)
Therophytes: Complete their life-cycle rapidly under favourable conditions and survive the unfavorable cold or dry season in the form of seed. Many desert plants are by necessity therophytes.

Therefore, the correct answer is option B.
