Consider the statements A, B and C and select the correct option.

115. Consider the statements A, B and C and select the correct option. Statement A: Animals that have had their genetic material manipulated to possess and express an extra (foreign) gene are known as transgenic animals. This statement is correct. The definition of a transgenic animal involves the introduction and expression of a foreign gene (transgene) in its genome. Statement B: Transgenic animals can be specifically designed to allow the study of how genes are regulated and how they affect the normal functions of the body. This statement is correct. Transgenic animals are widely used in research to understand gene function, regulation, and their roles in development and disease. Statement C: Over 95% of all existing transgenic animals are pigs and monkeys. This statement is incorrect. The vast majority of transgenic animals used in research are mice*, not pigs and monkeys. Based on the evaluation, statements A and B are correct, while statement C is incorrect. The correct option is (4). 4 116. All of the following lead to decrease in maternal and infant mortality rates, except (1) Better awareness about sex related matters: Increased awareness promotes family planning, safe practices, and timely medical care, leading to a decrease in mortality rates. (2) Better post-natal care: Comprehensive care for mothers and newborns after delivery significantly reduces complications and improves survival rates, leading to a decrease in mortality rates. (3) Decreased numbers of medically assisted deliveries: Medically assisted deliveries (e.g., in hospitals with skilled professionals) are crucial for managing high-risk pregnancies and complications during childbirth. A decrease in such deliveries would likely lead to an increase* in maternal and infant mortality rates, not a decrease. (4) Better detection and cure of STDs: Early detection and treatment of sexually transmitted diseases prevent adverse outcomes for both mother and child, thus decreasing mortality rates. The factor that does not lead to a decrease in maternal and infant mortality rates is (3). 3
