The false statement among the options is:
C. A heap is generally faster than a stack.
In general, stack memory allocation and deallocation are much faster than heap memory operations due to the way they are managed. Stack memory is managed through simple pointer adjustments, while heap memory management involves more complex operations for allocation and deallocation, which can introduce overhead.
