Another name for helper T cells is CD4+ (now options are correct), it is due to the presence of specific cell surface receptors.
<h3>What are T cells?</h3>
T cells are also called CD4- + positive cells have essential functions in the immune system by triggering adaptive immune responses.
These cells CD4- + positive cells contain specific cell surface receptors that can be identified by biochemical analyses.

NOTES FROM ME:
Sorry for the short answer, but I don't know too much about DNA analysis. Just in case that your really-really needed this answer, now you have it. I will do some additional research and I'll add more information, though comments, as I receive them.
Answer:
The process by which the egg cell (i.e., structure labeled B) is released from the ovary (i.e., structure labeled A) is known as ovulation
Explanation:
The egg cell, also known as an ovum, is the female gamete (i.e., the female reproductive sex cell), which is produced in the ovaries. The ovaries are the female gonads that contain many follicles, and each of them contains a single oocyte (immature egg cell). Ovulation occurs when a mature egg is released from the ovary during the menstrual cycle. During this process, the ovum moves to the fallopian tube where it can be fertilized by a sperm cell (male reproductive cell or male gamete). If fertilization occurs, the ovum moves to get implanted in the uterus and develop an embryo.
