ANS IS D
Output will be:
This is merit program
This is merit program
Thisis merit program...
Explanation:
-------sb.delete(14,21)-- will delete campus n space before it as it deletes from index 14 to 21.
--------sb.deleteCharAt(4)--will delete the space after the word "this" as space is at index "4".
