Which set has the same mean, median, and mode?

A. 8, 10, 12, 12, 14, 16

B. 5, 10, 15, 20, 20, 25

C. 6, 6, 12, 12, 18, 24

D. 9, 12, 15, 15, 21, 24

A.

Step-by-step explanation:

Sets A and C have a mode of 12 and a median of 12.

Calculate the means:

Set A: Mean = (8+10+12+12+14+16) / 6 = 12

Set C: Mean = (6 + 6 + 12+12+18+24) / 6 = 13

So the required set is A.
