Quiz: Indirect Grouping

In the Smallest String With Swaps problem, positions $0$ and $2$ are swappable, and positions $2$ and $4$ are swappable. Can you move a character from position $0$ to position $4$?

1. A.No, because there is no direct swap between $0$ and $4$
2. B.Yes, because $0$ and $4$ are in the same DSU component through position $2$
3. C.Only if you also have a swap between $0$ and $4$
4. D.Only if the characters at those positions are in sorted order
