P, Q and R are the points so that PR = 3 cm, QR = 5 cm and PQ = 8 cm. The number of circles passing through the points P, Q and R is :

1. 3
2. 2
3. 1
4. 0

Correct Option: D

According to question , we draw a figure of a line with P, Q and R points

Given that , PR = 3 cm, QR = 5 cm and PQ = 8 cm
PR + RQ = PQ
Hence, P, Q and R are collinear. Hence, no circle will pass through these three points.
