You are a most unusual person.

A. most

B. a mostly

C. mostly

D. the mostly

E. No correction required

Answer: Option E

Solution(By Examveda Team)

The phrase "a most" in the original sentence is not grammatically correct. The word "most" is used to indicate a high degree, but it should not be preceded by the indefinite article "a" in this context. The correct adverb to use in this sentence is "mostly," which means to a great extent or mainly.

Therefore, the corrected sentence is: "You are mostly unusual person."
