Is there any difference between the two statements?
char *ch = "IndiaBIX";
char ch[] = "IndiaBIX";
char *ch = "IndiaBIX";
char ch[] = "IndiaBIX";
Answer: Option
Explanation:
In first statement the character pointer ch stores the address of the string "IndiaBIX".
The second statement specifies the space for 7 characters be allocated and that the name of location is ch.
The second statement specifies the space for 7 characters be allocated and that the name of location is ch.

Yes, there is a difference, first statement apointer (ch) is a non-constant pointer to non-constant string because we can assign pointer to another string, sizeof(ch) depends on the compiler and operating system.
But in second statement array of string, the name of an array is a constant pointer, we cannot assign the string in array to another string,sizeof(ch)in this statement is 8.

So for both cases what is ch[0], ch[1], ch[2], ch and *ch?

Yes, you are Right @James.

By dereferencing the pointer and the array, won't they be the same?
Like ch[3] (pointer declaration of ch) == ch[3] (array declaration of ch)?
Like ch[3] (pointer declaration of ch) == ch[3] (array declaration of ch)?

It would be 9 characters - 8 plus one for NULL.
