Solution

The correct option is C Porogamy
When the pollen tube enters the ovary through the micropilar end and into the synergids through the filiform apparatus, the process is called porogamy.

If the pollen tube enters through the chalazal end, it is called chalazogamy.

If the pollen tube enters by penetrating the integuments on the lateral side, it is called mesogamy.
