Q.

Let be the set of all such that

Then which of the following is (are) correct?

  1. A

  2. B

  3. C

  4. D

Solution

As , is bounded between and , and . Also for large . So the expression behaves like

For the limit to be , the dominant factor in the denominator must grow without bound, which requires , i.e. .

Checking each option:

(A) . Fails.

(B) . Holds.

(C) . Holds.

(D) . Boundary case, fails the strict inequality.

Correct options are (B) and (C).
