(a)
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:
