**Core Concept**
Lignocaine (lidocaine) is a local anesthetic and antiarrhythmic medication that works by blocking sodium channels in nerve cells and cardiac muscle cells. Its side effects are primarily related to its pharmacological action on the nervous system and cardiovascular system.

**Why the Correct Answer is Right**
Lignocaine's side effects include central nervous system symptoms such as dizziness, seizures, and tremors due to its effect on sodium channels in the brain. It can also cause cardiovascular effects like hypotension, bradycardia, and cardiac arrest by blocking sodium channels in the heart. Additionally, lignocaine can cause allergic reactions, methemoglobinemia, and systemic toxicity with high doses.

**Why Each Wrong Option is Incorrect**
**Option A:**
This option is incorrect because the correct side effects of lignocaine are not listed here.

**Option B:**
This option is incorrect because the specific side effects of lignocaine are not detailed here.

**Option C:**
This option is incorrect because it is a known side effect of lignocaine that is not listed in the correct answer.

**Clinical Pearl / High-Yield Fact**
When using lignocaine, it's essential to be aware of the maximum recommended dose (7 mg/kg) to avoid systemic toxicity. Also, lignocaine can be metabolized by liver enzymes, and its clearance can be affected by liver disease.
