The correct option is
B Rectangle moves in a way: 90 – 180 – 90 – 180 (Anti – Clockwise)
Circle moves in a way: +a; -2a; +a; -2a starting in anti- clockwise direction.
(If 2a is the length of a side of the square)
And, half of the line moves by 90 first and then the whole structure moves by 90 in anti – clockwise direction.
