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.

Answer:
The dependent variable - the cholesterol level
Independent variables are the exercise and the drug.
Explanation:
A variable is a factor that can be modified or change. It is the factor that can be measured, altered, controlled in research or the experiment. It can be dependent or independent of their effect.
The independent variable is the factor of the experiment that controlled or manipulated by the researcher and it is considered to have a direct effect on the dependent variable whereas the dependent variable is being checked or tested.
So, in this experiment, the variable that is being tested is the cholesterol level that means it is a dependent variable. The independent variable here is exercise and drug as they manipulate and have an effect on the direct variable.
Thus, the correct answer is -
The dependent variable -the cholesterol level and
independent variables - exercise and the drug.
