**Core Concept**
During pregnancy, the use of certain medications is strictly regulated due to their potential teratogenic effects on the fetus. The management of pain and other medical conditions in pregnant women requires careful consideration of the risks and benefits of various pharmacological interventions.

**Why the Correct Answer is Right**
The correct answer is a medication that is considered safe for use during pregnancy, typically because it is not absorbed by the fetus or has a minimal risk of teratogenicity. For example, acetaminophen (paracetamol) is often used to manage mild to moderate pain in pregnant women, as it is not significantly absorbed by the fetus and has a low risk of adverse effects.

**Why Each Wrong Option is Incorrect**
**Option A:** This medication is a known teratogen and should be avoided in pregnancy, causing birth defects such as cleft palate and heart defects.
**Option B:** This medication is a corticosteroid, which is contraindicated in pregnancy due to its potential to cause fetal growth restriction and other complications.
**Option C:** This medication is a nonsteroidal anti-inflammatory drug (NSAID), which is generally contraindicated in pregnancy due to its risk of premature closure of the ductus arteriosus and other complications.

**Clinical Pearl / High-Yield Fact**
When managing pain in pregnant women, always consider the lowest effective dose and shortest duration of treatment to minimize the risk of adverse effects on the fetus.

**Correct Answer: C. Acetaminophen (Paracetamol)**
