F = {A → B, B → C, C → A}
G = {A → BC, B → AC, AB → C, BC → A, AC → B} 

Which of the following option is correct regarding FD sets given above?

(A) F⊃G
(B) F⊂G
(C) F≡G
(D) Incompatible


Answer: (A)

Explanation: Every FD of G can be derived using FD set of F but C → A of F cannot be derived using FD set of G. Therefore, F covers G but G not covers F, i.e., F⊃G

So, option (A) is correct.
