Please explain your answer.

Next, consider an explicit-list based dynamic memory allocator with the following properties blocks and payloads are word-aligned, with a word size of 8 bytes e all blocks have a header and footer word used to store the block size & allocated bit free blocks additionally have next and prior pointers for free-list maintenance . allocated blocks that have no room for payload are not permitted C. What is the minimum size of a block? (a) 8 bytes (c) 32 bytes (b) 16 bytes (d) 40 bytes D. Given a payload request of 50 bytes, what is the minimum block size to be allocated? (a) 56 bytes (c) 82 bytes (b) 72 bytes (d) 88 bytes E. How much space is lost to internal fragmentation for the block described in part D? (a) 8 bytes (c) 22 bytes (b) 14 bytes (d) 32 bytes
