B Correct answer
Explanation

 It is clear that 12 men = 16 women or 3 men = 4 women.  Therefore, 18 men + 8 women =18 * (4 / 3) women + 8 women  = 24 + 8 = 32 women 
Now, 16 women can complete the work in 12 days. So, 32 women will do it in 6 days. ((12 * 16) / 32 = 6 days).  It is the correct answer.
