► There are two possibilities for a
► Case 1 : a is even
• 6a  = Even x Even = Even
• 6a + 12 = Even + Even = Even
► Case 2 : a is odd
• 6a = Even x Odd = Even
• 6a + 12 = Even + Even = Even
► In both the cases the answer is even, so the information provided is inconsistent.

If you put a=1 in (6a+12) the answer is even. I tried till a=12 and the answer was odd only in one case i.e when a=7. based on one case we can't say that a is odd so the information is inconsistent. (Option D)
