Answer:

II only.

Explanation:

The block that you want executed if the if-expression (x<10) is true, has to be enclosed in { ... }.

I is wrong because it only declares "ans" conditionally. It wouldn't compile even.

II is correct.

III has the opening curly brace at the wrong place. It will not compile.
