To solve this question, we need to find the correct option that completes the sentence appropriately. Let's analyze each option:
A:
anyone
This option doesn't fit the context of the sentence. The sentence is expressing a preference for Johnson's, so using "anyone" doesn't make sense.
B:
someone else's
This option also doesn't fit the context. The sentence is referring to the person who cuts the hair, not someone else's hair.
C:
no one else
This option is appropriate because it emphasizes that the person cutting the hair is the best, and there is no one else who can do it as well.
D:
everyone
This option doesn't make sense in the context of the sentence. The sentence is referring to a specific person who cuts the hair, not everyone in general.
E:
nobody's
This option doesn't fit the context. The sentence is referring to the person who cuts the hair, not nobody's hair.
Therefore, the correct option is C:
no one else
