I think the answer should be A since statement1 is enough by itself.
Lets consider statement 1
a^2+c^2=202 given in the question
b^2+c^2=225 given in the statement1
b^2-a^2=(b-a)*(b+a)=23 b+a must be 23 and b-a must be 1 since a,b,c given positive and 23 is prime number. b=12 and a=11
if we know a and b then we could calculate c by using a^2+c^2=202.
Could you please elaborate?
It is not mentioned that a,b and c are integer values, so we cannot say that b+a =23 and b-a = 1
