# The question cons Assertion (A) :

Let O be the centre of the circle and AB be the chord

Construction: Draw, L is the midpoint of AB

Here,

OA = 10cm

AL = AB = 8cm

In ΔOAL,

OL2 = OA 2 – AL2

OL2 = (10)2 – (8) 2

OL2 = 100 – 64

OL = = 6cm

Thus, Assertion (A) is true.

Clearly, reason (R) given Assertion (A).

Hence, the correct choice is A.
