The correct option is A 7

The greatest number of things Roy can pack in each box is HCF of all types.

Factor of 28 = 1, 2, 4, 7, 14, and 28

Factor of 56 = 1, 2, 4, 7, 8, 14, 28, 56

Factor of 63 = 1, 3, 7, 9, 21, and 63

Common Factor = 1, 7

Therefore, HCF is 7 so the greatest number of things Roy can pack in each box is 7.
