Discussion

Explanation:

The ant will not go into the circles with centers B and C and radius = 1 m

The minimum distance that the ant has to traverse = the distance of the path A-H-G-D

HG = 1 m

AH = GD = 14 × Circumference of circle = π2

AH + GD = π m

∴ The ant must traverse (1 + π)m.

Hence, option (b).
