The capital English alphabets consist of 26 letters, of which 21 are consonants. The mirror image of some consonants will look identical to their original shapes. These consonants are:
- B
- C
- D
- E
- H
- I
- K
These letters, when reflected in a mirror, appear the same as their original shapes. Therefore, the number of consonants whose mirror images look identical to the original shape is 7.
Thus, the correct answer is (C) 7.
