Answer

Correct option: C.
Union of haploid sperm with haploid ovum to form diploid zygote.
Hence, fertilization is the union of haploid sperm with the haploid ovum to form a diploid zygote.
Fertilization is the process in which we observe the fusion of male and female gamete.
The parent organism produces a haploid sex gamete called sperm in males and ova or ovum in females.
When these haploid gametes fuse, It brings out fertilization and forms a diploid zygote, which further undergoes division to become an organism.
