Question

which condition is a risk to unborn babies whose mothers smoke?
○ decreased oxygen
○ lymph cancer
○ bacterial infection
○ viral infection

Explanation:

When a mother smokes, carbon monoxide in cigarette smoke can bind to hemoglobin in the blood, reducing the amount of oxygen that can be transported to the unborn baby. Lymph cancer is a type of cancer that is not directly a common risk specifically due to a mother smoking during pregnancy. Bacterial and viral infections are not the most typical and direct risks associated with a mother smoking during pregnancy compared to the oxygen - related issue.

Answer:

decreased oxygen
