Q. Let p and q real number such that `p!= 0`,`p^2!=q` and `p^2!=-q`. if `alpha` and `beta` are non-zero complex number satisfying `alpha+beta=-p` and `alpha^3+beta^3=q`, then a quadratic equation having `alpha/beta` and `beta/alpha` as its roots is

A

`(p^(3)+q)x^(2)-(p^(3)+2q)x+(p^(3)+q)=0`

B

`(p^(3)+q)x^(2)-(p^(3)-2q)x+(p^(3)+q)=0`

C

`(p^(3)-q)x^(2)-(5p^(3)-2q)x+(p^(3)-q)=0`

D
