A
a nucleus
B
an embryo
C
a zygote
D
a fetus
Explanation: 

Detailed explanation-1: -Zygote: The fertilized egg is called as a zygote. Zygote is an initial stage in baby development. It is also known as fertilized ovum formed from the union of male and the egg cells.

Detailed explanation-2: -Conception happens when sperm swims up through the vagina and fertilizes an egg in the fallopian tube. It happens in the hours or days after you have unprotected sex. After conception, the fertilized egg implants into the uterus and a pregnancy begins.

Detailed explanation-3: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.

Detailed explanation-4: -When egg and sperm meet, a zygote is formed and quickly begins dividing to become an embryo. As pregnancy progresses the embryo becomes a fetus.
