Select the option in which the numbers are related in the same way as are the numbers in the given set.

(9, 81, 6561)

(9, 81, 6561)
9² = 81, 81²​ → 6561
Logic: The pattern shows that each number is the square of the previous number.
Now, let's check each option:
Option (A): (3, 9, 27):
3²= 9, 9²= 81 $$\neq$$ 27 Does not follow
Option (B): (5, 25, 125)
5² = 25, 25² = 625 $$\neq$$ 125 Does not follow ​
Option (C): (2, 4, 16):
2² = 4, 4² = 16 Follow
Option (D): (4, 16, 64):
4² =16, 16² = 256 $$\neq$$ 64 Does not follow​
Thus, the correct option is (c) (2, 4, 16).
