Let `C_1` and `C_2` be respectively, the parabolas `x^2=y=-1` and `y^2=x-1` Let P be any point on `C_1` and Q be any point on `C_2` . Let `P_1` and `Q_1` be the refelections of P and Q, respectively with respect to the line y=x.
If the point `p(pi,pi^2+1)` and `Q(pi^2+1mu)` then `P_1` and `Q_1` are

Options

C. `(mu,mu^2+1)` =and `(mu,mu^2+1)`
D. `(pi,pi^2+1)` =and `(mu^2,1+mu)`

Answer
