# The question cons Clearly, reason (R) is true.

Assertion (A) :

OA = 13cm

OL = 12cm

In ΔOAL,

AL2 = OA2 – OL2

AL2 = (13)2 – (12)2

AL2 = 169 – 144

OL = = 5cm

Now, AB = 2 × AL = 2 × 5 = 10cm

Thus, Assertion (A) is true

Reason (R) and Assertion (A) are both true but reason (R) does not gives Assertion (A).

Hence, correct choice is B
