IMO C.
Being defeated is often only a temporary condition. Giving up is what makes it permanent.

Stmt 1:

If 0<x<1, then the answer is yes, otherwise its false.. not sufficient

Stmt2:

This tells us that either x<0, or 0<x<1.

If x<0, then the question stem evaluates to false, whereas for 0<x<1, it evaluates to true... not sufficient

Combining 1 and 2, we know that 0<x<1, which is enough to answer the question.

Hence (C). OA?
