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 P facing east.

The ant first turns 72∘ anticlockwise at P, and then does the following two steps in sequence exactly FIVE times before halting.

1. moves forward for 10cm.
2. turns 144∘ clockwise.

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

1. 
2. 
3. 
4. 

       A.  

       B. 

       C. 

       D. 

Using the above information, given in the question, we can easily draw the trace of an ant movement.

Here, PS = SQ = QT = TR = RP = 10 cm
