### Step-by-Step Solution:
1. **Identify the Compound**: The question asks about epichlorohydrin. We need to determine its structure and name.
2. **Draw the Structure**: Epichlorohydrin has a three-membered ring known as an oxirane ring (also referred to as an epoxide). The structure consists of:
- An oxirane ring (three-membered cyclic ether).
- A chlorine atom attached to one of the carbon atoms in the ring.
- A methyl group (–CH3) attached to the other carbon in the ring.
3. **Label the Atoms**: In the oxirane ring:
- Assign the first carbon in the ring as position 1.
- The second carbon in the ring will be position 2.
- The chlorine atom is attached to position 2.
4. **Name the Compound**: Based on the structure and the positions of the substituents:
- The compound can be named as 2-chloromethyloxirane.
- This indicates that there is a chlorine atom at the second position of the oxirane ring and a methyl group at the first position.
5. **Classify the Compound**: Epichlorohydrin is classified as an organochlorine compound. It is a colorless liquid with a pungent garlic smell.
6. **Select the Correct Option**: From the options provided, the correct name for epichlorohydrin is 2-chloromethyloxirane.
### Final Answer:
The name of epichlorohydrin is **2-chloromethyloxirane**.
