Solution
The correct option is A(3x−7)3(4x+5)
We know that if p(x) and q(x) are two polynomials, then p(x)×q(x)= {GCD of p(x) and q(x)}× {LCM of p(x) and q(x)}.
Now, it is given that one of the polynomial is p(x)=(4x+5)3(3x−7)2, the LCM is (4x+5)3(3x−7)3 and the GCD is (4x+5)(3x−7)2, therefore, we have:
