Solution

The correct option is C
Xenogamy

In xenogamy, male and female gametes are derived from different parents. Hence, it results in cross fertilisation. Cross pollination enables the fusion of characters of two genetically distinct plants of the same species therefore it introduces genetic recombination and variations in plants. Autogamy and geitonogamy do not exhibit cross fertilisation.
