If set C is {1, 2, 3, 4} and C – D = Φ then set D can be __________

1.	If set C is {1, 2, 3, 4} and C – D = Φ then set D can be ___________(a) {1, 2, 4, 5}(b) {1, 2, 3}(c) {1, 2, 3, 4, 5}(d) None of the mentionedI got this question during an interview.Query is from Algebraic Laws on Sets in division Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Right option is (c) {1, 2, 3, 4, 5} EASY EXPLANATION: C ∩ D should be equivalent to C for C – D = Φ.
