    Option D is correct

    eduncle-logo-app

    it is optically active due to chiral axis not due to chiral centre

    eduncle-logo-app

    Chiral centre required 4 diff grp attached

    eduncle-logo-app

    This compound don't have any POS and COS

    eduncle-logo-app

    Half of the molecule goes out of the plane due to steric crowding

    option D

    eduncle-logo-app

    it doesn't have any chiral center because to be chiral center carbon atom should have 4 different groups or atoms

    eduncle-logo-app

    but this molecule have chiral axis of symmetry.

    eduncle-logo-app

    if molecule have chiral axis of symmetry then it is optically active

    eduncle-logo-app

    so option A is absolutely wrong with, it doesn't have any plane so option C also wrong

    eduncle-logo-app

    it is an optically active compound so option B is wrong.

    eduncle-logo-app

    online option d is correct

    eduncle-logo-app

    got it??
