We can treat each group of people from the same nationality as a single entity. Therefore, we have 3 entities: the group of 4 Indians, the group of 5 Africans, and the group of 7 Japanese.

These entities can be arranged in a row in 3! ways. Within each entity, the people can be arranged in the entity in x! ways, where x is the number of people in the entity. Therefore, the total number of arrangements is:

3! x 4! x 5! x 7!

So the correct answer is (a) 4! 5! 7! 3!.
