**Core Concept**
The question tests knowledge of the physical properties of **methyl methacrylate**, a key monomer in the production of **acrylic resins** used in medical and dental applications. Understanding the **boiling point** of such substances is crucial for their handling and use.

**Why the Correct Answer is Right**
The correct boiling point of **methyl methacrylate** is around 100.5°C at standard atmospheric pressure. This value is specific to the substance due to its molecular structure and intermolecular forces.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect due to a significantly lower boiling point than expected.
**Option B:** Incorrect as it does not match the known boiling point of methyl methacrylate.
**Option D:** Incorrect due to being too high for the substance in question.

**Clinical Pearl / High-Yield Fact**
Remembering the boiling point of **methyl methacrylate** is crucial for safe handling in dental and medical procedures, as it influences the setting time and properties of the final acrylic product.

**Correct Answer:** C. 100.5°C
