C. 16
Explanation
Nia is currently 12 years old and three times as old as her sister, making her sister 4 years old. To find out how old Nia will be when she is twice as old as her sister, we need to determine the age difference between them. Currently, Nia is 8 years older than her sister. Since the age difference remains constant, Nia will be twice as old as her sister when her sister is half of Nia's current age, which is 6 years old. At that time, Nia will be 12 + 6 = 18 years old. Therefore, the correct answer is 16.
