The symbols move from quarter to quarter of the square, and each symbol also turns as it moves. Which figure comes next?

Each symbol moves one quarter clockwise, and as it moves it turns a quarter turn ANTICLOCKWISE (the arrow points up, then left, then down). This is not a turn of the whole figure, which would make the symbols turn clockwise. One more step moves each symbol on clockwise and turns it anticlockwise: (d). (a) turns the whole figure, (b) moves the symbols without turning them and (c) moves them anticlockwise.
