Answer & Solution
Correct answer: C. Never open; obligate self-pollination — bud-form structure
**Cleistogamy:** flowers that never open.
Self-pollination assured.
Found in some grasses (Oxalis, Commelina, Viola, Commelina benghalensis).
Often produced in addition to chasmogamous (normal open) flowers — bet-hedging strategy.
**Drawback:** no cross-fertilization → no genetic variation.
