Correct Answer: C

Rationale: Abortion is important due to the serious complications it can cause, such as infections and maternal death. Choices A and B are incorrect because ease of conducting or diagnosing abortion procedures does not inherently make abortion important. Choice D is incorrect because not all the options listed are reasons why abortion is important; only choice C highlights the critical aspect of potential complications.

Correct Answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.

Correct Answer: C

Rationale: The correct answer is C: Proliferative. The follicular phase corresponds to the proliferative phase during the menstrual cycle, characterized by the development of ovarian follicles. The luteal phase, on the other hand, corresponds to the secretory phase when the endometrium prepares for implantation. Choices A, B, and D are incorrect because they do not accurately reflect the phases being compared in the question.

Correct Answer: A

Rationale: The correct answer is A. Family planning aims to ensure that all couples and individuals have the basic right to decide freely and responsibly the number and spacing of their children. This promotes reproductive autonomy and allows individuals to make informed choices about their family size. Choices B, C, and D are incorrect because they involve imposing restrictions or decisions on family size rather than empowering individuals to make their own choices.

Correct Answer: D

Rationale: The correct answer is D. Expanded programs of immunization are not considered a strategy for family planning. Immunization programs focus on preventing diseases through vaccines and are distinct from family planning strategies, which aim to help individuals and couples plan their desired family size and spacing of children. Choices A, B, and C are all valid strategies for family planning. Integrating family planning services with other reproductive health programs, expanding access to family planning through non-public delivery systems, and targeting family planning services to priority groups are common approaches to improve the availability and effectiveness of family planning services.
