If `alpha,beta` are the roots of `x^2+p x+q=0a d nx^(2n)+p^n x^n+q^n=0a n di lf(alpha//beta),(beta//alpha)` are the roots of `x^n+1+(x+1)^n=0,t h e nn( in N)` a. must be an odd integer b. may be any integer c. must be an even integer d. cannot say anything

Answer

This is true only if n is aneven integer.
