Step-by-step explanation:
First, eliminate obvious wrong answers.
B:X
All multiples of 12 can always be divided by 3 or 4.
Then, go from top to bottom, skipping eliminated answers.
A:X
Composite: 4, 6, 8, 9, 10, 12, 14, 15
Odd: 1, 3, 5, 7, 9, 11, 13, 15, 17
Choice A has the number 9 in common between both rules.
C:_/(Imagine that's a check)
Even numbers are integers that when divided by 2, give back another integer (Zero is included in this rule). Those that don't follow this rule are considered odd numbers. Because of this, it's impossible to get an integer that is both odd <u>and</u> even.
Even: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18
Odd: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
