**Core Concept**
Plasma cholinesterase is an enzyme responsible for the breakdown of the neurotransmitter acetylcholine. Abnormal plasma cholinesterase activity can lead to a buildup of acetylcholine, which in turn can cause various systemic effects, including neuromuscular blockade and apnea.

**Why the Correct Answer is Right**
The buildup of acetylcholine in the neuromuscular junction leads to continuous depolarization of the muscle membrane, resulting in sustained muscle contraction and ultimately, paralysis. This is because acetylcholine normally acts as a neurotransmitter to stimulate muscle contraction by binding to nicotinic acetylcholine receptors on the muscle surface. With abnormal plasma cholinesterase, the normal breakdown of acetylcholine is impaired, leading to prolonged neuromuscular transmission and paralysis.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not directly related to the mechanism of abnormal plasma choline esterase on neuromuscular transmission.
**Option B:** This option is incorrect as it is not directly related to the effects of abnormal plasma cholinesterase on neuromuscular transmission.
**Option C:** This option is incorrect as it is not the primary mechanism by which abnormal plasma cholinesterase produces apnea.

**Clinical Pearl / High-Yield Fact**
One classic example of abnormal plasma cholinesterase is the genetic condition known as pseudocholinesterase deficiency, which can lead to prolonged apnea after administration of certain anesthetic agents, such as succinylcholine.

**Correct Answer: C.
