If the conics whose equations are `S_1:(sin^2theta)x^2+(2htantheta)x y+(cos^2theta)y^2+32 x+16 y+19=0` `S_2:(cos^2theta)x^2-(2h^(prime)cottheta)x y+(sin^2theta)y^2+16 x+32 y+19=0` intersect at four concyclic points, where `theta[0,pi/2],` then the correct statement(s) can be (a) `h+h^(prime)=0` (b) `h-h^(prime)=0` (c) `theta=pi/4` (d) none of these
