For the following question, choose the correct answer from the codes (a), (b), (c) and (d) defined as follows: Statement I is true, Statement II is also true; Statement II is the correct explanation of Statement I. Statement I is true, Statement II is also true; Statement II is not the correct explanation of Statement I. Statement I is true; Statement II is false Statement I is false; Statement II is true. Let `a , b , c , p , q` be the real numbers. Suppose `alpha,beta` are the roots of the equation `x^2+2p x+q=0` and `alpha,1/beta` are the roots of the equation `a x^2+2b x+c=0,` where `beta^2 !in {-1,0,1}dot` Statement I `(p^2-q)(b^2-a c)geq0` and Statement II `b !in p a` or `c !in q adot`
