Option 3 “34 inches” is the answer because the sum of two sides of the triangle must be greater than the third side. If this rule is not obeyed then the third side will not complete the triangle and it will be not be joined.
11+18<34 true
11+34<18 true
18+34<11 true
Therefore this is a complete triangle.
Hope this helps you. Have a nice day and keep smiling!!
