Questions asks the absolute value and none of the options gives an absolute value (Both of them gives ratios).

hence Option E)

From S1:OP:PQ=1:2
OQ=radius.It's not possible to calculate a single value for rad based on ratio.Insufficient
From S2:P=midpt of chord AB
Again this implies triangles OAP & OQP are congruent but gives no unique value can be calculated based on this.Insufficient.
Combining the two,we do get any absolute value for radius.

Statement (1) says PQ= 2OP, giving multiple values for the radius. Insufficient

Statement (2) has no relationship with the radius whatsoever, hence Insufficient

Together, (1) and (2) are clearly not sufficient.

Answer E.

Statement 1 gives a ratio so clearly insufficient
Statement 2 gives information that can already be inferred from the question stem so clearly insufficient
combining we don't get any new information
clearly the correct answer is option - E
