Question

Given the following sets, select the statement below that is NOT true.
A = {r, i, s, k, e, d}, B = {r, i, s, e}, C = {s, i, r}

C ⊂ A
B ⊆ C
C ⊆ A
B ⊂ A
B ⊆ A

Answer 1

C ⊂ A is true since all of set C is in set A. Also, set C is smaller than set A

B ⊆ C is false because 1) set B is larger than set C, and 2) the element 'e' is NOT in set C (but it's in B)


So we're done


This means that the answer is choice B
