What is the radial acceleration of B. w. r. t. C?

Question

OABC is a 4 – bar mechanism

            OA = 2cm, AB = 2.2 cm, BC = 2.5 cm 

            Fixed link OC = 3.5 cm

            OA rotates at 10 rad/s

            Extended OA meets extended CB at P

            PO = 6cm, PC =6.5 cm

What is the radial acceleration of B. w. r. t. C?

(a) 40 cm/s²                 (b) 80 cm/s²                 (c) 160 cm/s²               (d) 320 cm/s²
