Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.

The correct answer is D. Separate injections of tetanus toxoid and tetanus antitoxin in different sites on this visit to ensure active and passive immunization.
Explanation:
Tetanus is a bacterial infection caused by Clostridium Tetany, this occurs as an object with the bacteria cuts the skin or causes a wound. Due to this, every time there are lacerations or cuts in an accident it is important to provide protection against Tetanus. This commonly occurs through the Tetanus vaccine also know as tetanus toxoid that is administered during childhood and works through passive immunization. However, if the patient has not been previously immunized he/she must receive tetanus toxoid and separately tetanus antitoxin that prevents tetanus through active immunization.
According to this, in the case presented the patient should have separate injections of tetanus toxoid and tetanus antitoxin (Option D) because this patient has not been previously immunized and therefore requires both tetanus toxoid and tetanus antitoxin, additionally, as each of these is different, they should be administered separately, but almost at the same time to prevent tetanus infection.
