Which of the following is NOT listed as an environmental factor in pregnancy in the material?

• A. Genetic predisposition
• B. Air quality
• C. Water quality
• D. Noise levels

Answer: (A)

Environmental factors are external conditions and exposures that can affect a pregnancy, such as air quality, water quality, and noise levels. These are about what the environment presents to the pregnant person. Genetic predisposition, however, refers to inherited traits in the genome—factors inside the person’s own biology rather than the external environment. It can influence how someone responds to exposures, but it isn’t itself an environmental exposure. So genetic predisposition is the one not listed as an environmental factor.
