Answer

Array

Option : A
Explanation :
Assume starting address of string is 100 to make the whole expression is easy to understand.

Note: Whenever we have characters in the arithmetic expressions, we can replace those with their ASCII values
strlen (100 + x + 11 - x - 1)[assume x has the ASCII value of I]
⇒Strlen(110)
is printed
It gives address of second last character in the string. So it prints length 2.
