If you release A and make C a pin, A will obvioulsy rotate clockwise. So just to iterate oldrollas comments the reactions at A will be down and to the left.
Don't confuse yourself with whether or not the arrows are pointing at the pin cause you could place a force arrow upwards on either side of the pin, hence 1 would be pointing at the pin and the other wouldn't but the force is still in the same direction.
