Statement 1 is just giving the coordinates of C, so we cannot find the coordinates of the midpoint.
So, (1) is NOT SUFFICIENT.
Statement 2 is just giving the coordinates of D, so we cannot find the coordinates of the midpoint.
So, (2) is NOT SUFFICIENT.
Combining statements (1) and (2), we can definitely answer the question as we know the coordinates of C and D, both. So applying the midpoint formula, the question can be answered.
[spoiler]The correct answer is C.[/spoiler]

When we find the coordinates of the midpoint, it is [{a + (1 - a)}/ 2, {(1 - b) + b}/2] = (1/2, 1/2)ov25 wrote:I would leave this to the experts! I think it's E
So, we are able to find the coordinates. Hence, C is the right answer.
