Final Answer :
D
Explanation :
Polychlorinated biphenyls (PCBs) are toxic to humans because they can accumulate in the fatty tissues of the body and disrupt normal cellular processes. This can lead to a variety of health problems, including weakened immune systems (A), liver damage (B), and brain damage to children exposed in the womb (C). However, there is no evidence to suggest that exposure to PCBs causes skin cancer (D).
