**Core Concept**
Cobra venom is a complex mixture of bioactive molecules, including neurotoxins and hemotoxins, which cause various systemic and local effects upon injection into the human body. The venom contains a group of enzymes that are responsible for its toxic effects, primarily affecting the nervous system and cardiovascular system.

**Why the Correct Answer is Right**
The correct answer to this question is not provided as it is missing from your prompt. However, cobra venom is primarily composed of a phospholipase A2 enzyme that causes local tissue damage, as well as a group of neurotoxins, including cobratoxin, which blocks acetylcholine receptors at the neuromuscular junction, leading to flaccid paralysis. The venom also contains other enzymes such as hyaluronidase, which increases the spread of the venom through tissues.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the correct composition of cobra venom.
**Option B:** This option is incorrect because it is too vague and does not accurately describe the primary components of cobra venom.
**Option C:** This option is incorrect because it is not a recognized component of cobra venom.

**Clinical Pearl / High-Yield Fact**
Cobra venom contains a potent neurotoxin that can cause flaccid paralysis, which can be reversed with antivenom if administered promptly.
