(a)
Interpretation: A plane of symmetry for the given molecule is to be indicated.
Concept introduction: Molecule having asymmetric center shows optical activity except meso compounds. Asymmetric center is a stereocenter which arises in hydrocarbons if the carbon is bonded to four different groups.
A compound with asymmetric centers possesses a plane of symmetry, so it is superimposable on its mirror image, thereby the compound is achiral.
