**Core Concept**
The active management of the third stage of labor (AMTSL) is a critical component of postpartum care, aiming to reduce maternal and neonatal mortality by preventing excessive bleeding (postpartum hemorrhage, PPH). It involves a series of interventions to facilitate placental delivery and promote uterine contraction.

**Why the Correct Answer is Right**
The correct answer involves a series of evidence-based steps: administration of uterotonics (oxytocin or ergot alkaloids), controlled cord traction (CCT), and uterine massage. These measures help to reduce blood loss by promoting placental delivery, stimulating uterine contractions, and preventing atony. The administration of uterotonics is a key component, as it helps to reduce bleeding by stimulating the uterus to contract.

**Why Each Wrong Option is Incorrect**
**Option A:** This option may be incorrect, as the specific uterotonic agent used is not as critical as the fact that a uterotonic is administered. However, the administration of uterotonics is a key component of AMTSL.

**Option B:** This option is incorrect because controlled cord traction (CCT) is a recommended component of AMTSL. CCT helps to facilitate placental delivery and reduce blood loss.

**Option C:** This option is incorrect because uterine massage is a recommended component of AMTSL. Uterine massage helps to stimulate uterine contractions and reduce blood loss.

**Clinical Pearl / High-Yield Fact**
A mnemonic to remember the components of AMTSL is "CUT": Controlled Cord Traction, Uterotonics, and Uterine Massage.

**Correct Answer:** A.
