The list Cards contains 4 items: "Heart", "Spade", "Club", "Diamond".
The loop iterates with i taking values 0 and 1 (from range(2)).
Inside the loop, the index is determined by random.randint(1, i+2).
For i = 0: random.randint(1, 2) yields 1 or 2.
This corresponds to cards "Spade" (index 1) or "Club" (index 2).
For i = 1: random.randint(1, 3) yields 1, 2, or 3.
This corresponds to cards "Spade", "Club", or "Diamond".
Option (A), Spade#Diamond#, is valid:
First selection: index 1 → Spade. Second selection: index 3 → Diamond.
Other options are invalid because they either start with Heart (index 0), which is not selectable,
or repeat indices that are not possible within the given ranges.
Thus, option (A) is confirmed as valid.
