Solution

The correct option is C Commelina
Commelina has cleistogamous flowers i.e. flowers that do not open. Hence these flowers are pollinated from within (autogamy) and do not need pollinating agents. Because of the close proximity of the male and female reproductive parts in these flowers, they undergo the process of self pollination.

Salvia and fig flowers undergo entomophily (insect pollination) and therefore need insects as pollinating agents.

Zostera flower undergoes hydrophily and therefore needs water as the pollinating agent.
