Q. Advantage of cleistogamy is
A) Higher genetic variability
B) More vigorous offspring
C) No dependence on pollinators

Explanation
[Solution from source] Cleistogamous flowers never open, so pollen falls directly on the stigma of the same flower and seed set is assured even without pollinators. Because this is self-pollination, it reduces rather than increases genetic variability. Answer (3).
