Choose correct al

Answer :


Given that OP = 5 cm


And AB = 24cm


We know that a perpendicular drawn from the center of a circle on its chord bisects


the chord.


AP = PB = 12 cm


In the right angled ΔOAP using Pythagoras theorem,


OA2 = OP2 + AP2


OA2 = 52 + 122


OA2 = 25 + 144


OA2 = 169


OA = 13cm


Hence, The correct option is B.
