The pseudocode statement "Display str[length(str)- 1]" will display the last character in the string "ABC". Here, "length(str)" will return the length of the string as 3, and since the index starts from 0, the last character will be at index 2. So, by subtracting 1 from the length, we can access the last character of the string using the index value 2. Therefore, D is the correct choice.
