The letters D, G, I, I, and T can be used to form 5-letter strings such as DIGIT or DGIIT. Using these letters, how many 5-letter strings can be formed in which two occurrences of letter I are separated by at least one other letter?

(A) 12

(B) 18

(C) 24

(D) 36

(E) 48

My choice is A. But OG guide says D. Can someone help please?
