Answer 1

Answer: (A)

Question can be answered by using any one statement alone, but not by using other statement alone.

Answer 2

First we use statement I, we know that $\log_{96} 70 = k$(say)
Now, $\log_{70} 96 = \log^{1/96} 70 = \frac{1}{k}$
Thus, I statement is enough to get the answer.
In case of Statement II, we cannot get the solution using second statement alone.
The correct option is (A)
