Answer
Reversed lock order causes circular wait. Frame the concept in practical terms so you can explain it during interview discussion.
Deadlocks can occur when two or more threads try to acquire multiple locks in a different order. If Thread A locks A then B, and Thread B locks B then A, they can end up waiting indefinitely for each other. To avoid this, always acquire locks in the same order.
