**Answer: (3) 6930 cm**

**Explanation:-**

The length of their steps = 63 cm, 70 cm and 77 cm

The minimum distance each should cover so that all can cover the distance in complete step = L C M of 63, 70 and 77

Factors of 63 = 3 x 3 x 7

Factors of 70 = 2 x 5 x 7

Factors of 77 = 11 x 7

L C M = 2 x 3 x 3 x 5 x 7 x 11 = 6930

Hence, the answer is (3) 6930 cm.
