Correct Answer - Option 1 : only (ii)

**Calculation:**

Gien, 0 < a < 1, squaring both sides, 0 < a^{2} < 1

Let us go through the statements:

(i): subtracting 1 from the inequality equation:

-1 < a2 - 1 < 0

That is, a2 - 1 < 0 , hence (i) is false.

(ii): adding 1 to the inequality equation:

1 < a2 + 1 < 2

That is, 1 < a2 + 1, hence (i) is true

Now in the options, w can see that, only option 1 is possible as options 2 and 4 are not possible as the statement (i) is false.

Also, option 3 is not possible as we know statement (ii) is already true.

**∴ Only statement 2 is possible.**
