28228 An alkene \((A)\) \(C_{16}H_{16}\) on ozonolysis gives only product \((B)\) \(C_8H_8C.\) \((B)\) also can be obtained by hydrolysis of the product obtained by reaction between cyano benzene and \(CH_3MgBr.\) \((A)\) can show geometrical isomerism and it can decolourise \(Br_2\) water. \((B)\) on treatment with \(SeO_2\) produces \((C).\)Which is not correct about \((A)\) ?

1 \(A\) is optically inactive
2 On catalytic hydrogenation 'trans' form of \(A\) produces racemic mixture
3 A can be prepared by Witting reaction on acetophenone with \(Ph_3P = C(CH_3)Ph.\)
4 On treatment with per acid followed by hydrolysis 'trans' form of \(A\) produces racemic mixture
