Fertilisation occurs when a sperm and an egg fuse.

Detailed explanation-1: -Fertilisation occurs when a sperm fuses with the female act during intercourse and further forms an egg that gets implanted in uterus of the female. The sperm travels through the fallopian tube and penetrates the zona pellucida layer of the ovum (female egg) and fuses with it which forms zygote (fertilized egg).
Detailed explanation-2: -In humans, fertilization takes place in females, in the oviduct or the fallopian tube. For fertilization, the motile sperm moves towards the egg and fuses to form the zygote. Thus, the correct answer is option D.
Detailed explanation-3: -Conception happens when sperm fertilizes the egg. Once conception occurs, your provider places the created embryo inside the uterus that will carry the pregnancy for implantation.
Detailed explanation-4: -When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus. This results in the formation of a fertilized egg or zygote.
Detailed explanation-5: -Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
