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.
