Explanation / Answer

Crater C is oldest as it has subcraters from both A and D, so it was formed before A and D,

next is crater D was formed next as it has ray from A overlapping with it, so it must have formed before A

Next is A and finally the youngest is B as it overlaps over A and obviosly had to have formed after A was formed.

Thus, oldest C>D>A>B youngest
