Solution

The correct option is B $1$
The order of rotational symmetry refers to the number of times a shape map onto itself during a $360^{\circ}$ rotation. Order of rotational symmetry of a semicircle is $0$ because when the semi circle is rotated, it only coincides with itself after one whole rotation.
