An ant walks in a straight line on a plane leaving behind a trace of its movement. The initial position of the ant is at point $\text{P}$ facing east.

The ant first turns $72^{\circ}$ anticlockwise at $\text{P},$ and then does the following two steps in sequence exactly FIVE times before halting.

1. moves forward for $10 \; \text{cm.}$
2. turns $144^{\circ}$ clockwise.

The pattern made by the trace left behind by the ant is

A.

B.

C.

D.

Here, ${\color{Blue}{\text{PS = SQ = QT = TR = RP = 10 cm}}}$
Correct Answer $:\text{C}$
