Solution

The correct option is C Porogamy
Porogamy is the process, which is defined as entrance of pollen tube in a seed plant through the micropyle.
Chalazogamy is a process of fertilization in which the pollen tube penetrates to the embryo sac through the tissue of the chalaza.
Mesogamy is a pollen tube that enters the embryo sac through the funiculus or the integument.
Apogamy is the development of an embryo without the occurrence of fertilization. Hence, option A is correct.
