If C = {x | x is an even integer}, which of the following is a subset of C?

If C = {x | x is an even integer}, which of the following is a subset of C?

Step 1: Understand what the set C represents. C is the set of all even integers, which includes numbers like -4, -2, 0, 2, 4, 6, and so on.
Step 2: Identify the set we are checking to see if it is a subset of C. In this case, the set is {2, 4, 6}.
Step 3: Check each element in the set {2, 4, 6} to see if they are even integers.
Step 4: Confirm that 2 is an even integer, 4 is an even integer, and 6 is an even integer.
Step 5: Since all elements in {2, 4, 6} are even integers, we conclude that {2, 4, 6} is a subset of C.
