Answer from cs61c-eg (Ramanarayan Vasudevan 15938560) for Question 1
B and C are true. Consider the case where i am attempting to find some memory but malloc finds that it has no memory. Malloc then asks the operating system for more memory. If the amount of memory is larger than NALLOC than i will get exactly the amount of memory i want and the number of free blocks will be unchanged. However if the memory i ask for is less than NALLOC than i will get the memory i want and the rest will become free memory.
