What leads to deadlock in the dining philosophers problem?

Too many philosophers
Not enough chopsticks
Philosophers waiting on each other for resources
All philosophers thinking at the same time

The correct answer is: Philosophers waiting on each other for resources

Deadlock in the dining philosophers problem occurs when all philosophers are waiting on each other to release resources. This situation can arise if each philosopher holds onto one resource and is waiting for a second resource which is being used by another philosopher. This creates a loop of dependencies where no one can move forward and results in a deadlock. The other options, such as too many philosophers or not enough chopsticks, do not directly contribute to a deadlock situation in this problem. Additionally, the option of all philosophers thinking at the same time does not necessarily lead to a deadlock, but it can cause inefficiency in the allocation of resources.
