The correct conversion is b. 86 m = 86 000 cm.

Here's why:

a. 72.4 mm = 7.24 cm is incorrect because 1 cm = 10 mm, so 72.4 mm = 7.24 cm.

b. 86 m = 86 000 cm is correct because 1 m = 100 cm, so 86 m = 86,000 cm.

c. 59 m = 590 cm is incorrect because 1 m = 100 cm, so 59 m = 5,900 cm.

d. 55 m = 0.55 cm is incorrect because 1 m = 100 cm, so 55 m = 5,500 cm.
