Contraceptive methods are birth control and planning strategies. Withdrawal before ejaculation is the least likely method that prevents fertilization. Thus, option D is correct.
<h3>What are contraceptives?</h3>
Contraceptives are the birth control methods used by males and females to prevent the fertilization of sperm and eggs. Diaphragm, vasectomy, IUD, condoms, withdrawal before ejaculation, etc. are some of the contraceptive methods.
The diaphragm is the barrier method used by females to prevent sperm entry inside the vagina. Similarly, IUD is inserted inside the uterus of the female to prevent fertilization.
Vasectomy is the irreversible contraceptive method in which the vas deferens of the male reproductive system are tied. The withdrawal before ejaculation is least likely to prevent fertilization but is not a reliable method.
Therefore, withdrawal before ejaculation is not an effective contraceptive method.

False, from the information provided, mutations in this breast cancer-associated gene tend to be primarily synonymous substitutions.
<h3>What is breast cancer?</h3>
One type of cancer that begins in the breast is breast cancer. It may begin in either the left or right breast. Although men can also develop breast cancer, breast cancer affects almost exclusively women. It's crucial to realize that the majority of breast lumps are benign and not cancerous (malignant). Breast tumors that are not cancerous are abnormal growths that do not spread to the exterior of the breast. While most benign breast lumps are not life threatening, some of them can raise a woman's risk of developing breast cancer. Any breast lump or change should be examined by a medical professional to determine whether it is benign or malignant (cancer) and whether it may increase your risk of developing cancer in the future.
Thus from above conclusion we can say that false, from the information provided, mutations in this breast cancer-associated gene tend to be primarily synonymous substitutions.
