The false statement among the provided options is:
**"A heap is generally faster than a stack."**
In general, stack operations (such as push and pop) are faster than heap operations (such as malloc and free in C/C++), because stack memory allocation and deallocation are simpler and typically involve just moving a pointer, whereas heap allocation requires more complex bookkeeping to manage free memory blocks. Therefore, this statement is false.
