Answer 1

It is B)

a [ x ] can be written as *( a + x ) .

and a [ x ][ y ] can be written as *(*( a + x ) + y)). 

char** x and char* x[]  and char x[ ][ ] are ways of expressing the same thing .

Answer 2

Answer : B

Here arg is a pointer to a pointer of type character 

Char **arg ===> Char *(*arg)  Here" * " is used as pointer indirection which has a associativity from right to left .

we can use array name and pointer interchangeably 

we can write it in the form of array like this arg [][] means first" * "on arg (*arg) will represent arg[] and the second one (**arg) as arg[][] .
