No data. Can reduce prolactin, may reduce milk production.

• A. No data. Can reduce prolactin, may reduce milk production.
• B. Increase prolactin
• C. No effect on prolactin
• D. May increase prolactin

Answer: (A)

Prolactin is the hormone that drives milk production. When a drug lowers prolactin, milk production tends to drop; when prolactin is increased, milk production can rise. Even if there isn’t data provided, the idea that the drug can reduce prolactin makes it plausible that milk production could be reduced too. That’s why stating “No data. Can reduce prolactin, may reduce milk production” fits the biology best. The other ideas—prolactin increasing, no effect on prolactin, or a potential increase in prolactin—do not explain a decrease in milk production.
