**Core Concept**
In pregnancy, normalcy is defined by the absence of complications, allowing the continuation of the pregnancy. The American College of Obstetricians and Gynecologists (ACOG) guidelines provide criteria for a normal pregnancy, including a regular menstrual cycle, normal uterine size, and adequate fetal growth. The maintenance of a normal pregnancy requires close monitoring of maternal and fetal health.

**Why the Correct Answer is Right**
A normal pregnancy can continue if the following conditions are met:
- The pregnancy is beyond 12 weeks of gestation.
- The fetal heart rate is between 100-160 beats per minute.
- The maternal blood pressure is within normal limits.
- The absence of any contraindications to pregnancy, such as severe medical conditions or substance abuse.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify any criteria for a normal pregnancy, making it non-definitive.
**Option B:** This option is incorrect because it only mentions one aspect of a normal pregnancy, not providing a comprehensive criteria.
**Option C:** This option is incorrect because it is too vague, not providing any specific criteria for a normal pregnancy.

**Clinical Pearl / High-Yield Fact**
In pregnancy, regular monitoring of fetal growth and maternal health is crucial for the continuation of a normal pregnancy. This includes regular ultrasound scans, blood pressure checks, and fetal heart rate monitoring.

**Correct Answer:** C.
