(a)

Interpretation Introduction

Interpretation:

The object, a circular clock face is asymmetric or not has to be given.

Concept Introduction:

Symmetric:

When a molecule is rotated by an axis of symmetry, the original and the rotated species will be indistinguishable from one another are said to be symmetric.  In simple terms, when a molecule is divided into two parts, if the two parts are equal means they have symmetry.

Example:

Asymmetric:

The molecules which has no plane of symmetry or center of symmetry are said to be asymmetric.  It depends on the presence of asymmetric atom in the molecule.  When a molecule is divided into two parts, if the two parts are unequal means they are asymmetric.

Example:
