ANS. b. #

# is an operator used to convert a parameter to string
# should always be followed by a formal parameter (in below example parameter x)

Ex:
#define SAM(x) #x
printf(SAM(Hello)); // prints Hello

In other cases
char a = 0x10, b;
char *p = &b;

a. a&&*p is valid
b. *p is valid
c. a>>*p is valid
