Answer 1

static char var $=$ A variable located in data section of memory

$m= malloc(10); m= null; $ Here, free(m) is missing: So, a lost memory which cannot be freed

$char * ptr[10];$ Sequence of 10 memory locations to store addresses

register int var1; Request to allocate a CPU register to store data

Answer is A.
