B Correct answer
Explanation

Diploidy (2n chromosome number) in higher animals is maintained by syngamy - the fusion of male and female gametes during fertilization. This restores the diploid state in the zygote. Plasmogamy is fungal cytoplasm fusion, and dichogamy refers to timing differences in sexual organ maturity.
