Question 92Safety & Environmental - 1st Asst/Chief

The correct answer is A) mutagen. A mutagen is a substance that can cause genetic changes or mutations in the DNA of sperm or egg cells, which can then be passed on to offspring. This is the definition of a reproductive health hazard related to genetic changes, as described in the question. The other answer choices are incorrect because: B) carcinogen refers to a substance that can cause cancer, C) teratogen refers to a substance that can cause birth defects, and D) cryogenic refers to the use of extremely low temperatures, which is not relevant to the reproductive health hazard described.
