Answer from cs61c-cl (Hiroki Terashima 16032281) for Question 1
"A" is not necessarily true because if there is not a big-enough space in the free list, another large chunk is obtained from the operating system and linked into the free list, thereby increasing the number of free blocks.  So "C" is true. "B" could be true if the large chunk obtained from the operating system was exactly the same size as what we were looking for.

True: B and C
