It will be c. #3pi/2, 4r#

Explanation:

As the body will be stationary. We will take that point as #r#. Every revolution it will take will be of #90^@#. Hence after 3 seconds it will be #270^@#. That means in radian value it will be #3pi/2#.

Now, the body where it was stationary was #1r#. Hence after revolving for 3 seconds it will be #4r# because after the next second it will be back on to #1r#

Therefore the answer will be c. #3pi/2 , 4r#
