Answer:
3. A rectangle
Explanation:
It moves two (02) units in one direction then changes its direction through 90 degrees, then it moves one (01) unit and changes direction and again moves two (02) units and turns and finally it moves one (01) unit.
It cannot be circle because it turns through 90 degrees.
It cannot be square because its length of movement is different. i.e. 1 vs 2.
Therefore, it's a rectangle.
