Final answer:
The use of castor oil to treat constipation in pregnant women is not recommended.
Step-by-step explanation:
The answer to the question is C) Not recommended. Castor oil is often used as a home remedy for constipation, including in pregnant women, but its use is not recommended by medical professionals.

Castor oil can induce strong contractions in the uterus and may lead to premature labor, which can be harmful to both the mother and the baby.
