2. **Option B:** Armpits: Eccrine glands are more abundant in the armpits, but multiple epidermoid cysts are rare here.
3. **Option C:** Face: Epidermoid cysts can occur on the face, but the primary site is not multiple cysts.
4. **Option D:** Scalp: Epidermoid cysts are common on the scalp, but multiple cysts are rare.

**Why Each Wrong Option is Incorrect:**

Apart from the options mentioned above, epidermoid cysts can also occur in other areas like the chest, back, and extremities. However, the primary reason for choosing option D (Scalp) is that it represents the most common site of epidermoid cysts, which is why it is the correct answer despite being less specific than other options for multiple cysts.
