Lead exposure can cause difficulties with pregnancy.

Lead exposure can cause difficulties with pregnancy.

• A. Other reproductive problems (men/women)
• B. Difficulties with pregnancy
• C. No reproductive effects
• D. Increased fertility

Answer: (B)

Lead exposure harms reproductive health and is known to affect pregnancy outcomes. Lead can cross the placenta and influence both maternal health and fetal development, raising the risk of miscarriage, preterm birth, and low birth weight, among other complications. Because the statement directly describes difficulties during pregnancy, it best reflects the pregnancy-specific risks associated with lead exposure. The other options either broaden the scope beyond pregnancy, claim no effects, or incorrectly suggest increased fertility, which isn’t supported by evidence.
