The correct anser is D.

Circumference = 24πm, Width of track= 2 m 

As we know that circumference = 2πr
Therefore, 2πr = 24π

                   r = 12m

Now, Radius of outer circle = Radius of inner circle + Width of the track = 12 m + 2 m = 14 m
Again, Circumference of outer circle = 2πR = 2 X 3.14 X 14 = 88 m 

Hence, the quantity of wire required to surround the path completely is 88 m.
