============================================================
Theory
============================================================
Quantity A: The average (arithmetic mean) of \(3^2,3^4,3^6\)
=> Average = \(\frac{3^2 + 3^4 + 3^6}{3}\) = \(3 + 3^3 + 3^5\) > \(3^4\)
Clearly, Quantity A > Quantity B
So, Answer will be A.
Hope it helps!
