Solution

The correct option is B 2 cm

Construct triangle ABC of given measurements.

Draw perpendicular bisectors of sides AB and BC.

Mark the intersection of the perpendicular bisectors as O.

Draw a circle with O as the centre and OA as radius.

By measuring, the radius of the circumcircle is 2 cm.
