Explanation / Answer

(11)
   (a) Initially variable count is initialized to 0.
   (b)   do-while loop iterates i from 0 to 11. When i value is 11 the loop gets stopped.
   (c) So the given code prints 11 times.

   Hence correct option is (A)

(12)
   (a)   Initially variables sum and item are initialized to 0
  
   sum = 0, item = 0 => item = 1, sum = 1
   sum = 1, item = 1 => item = 2, sum = 3
   sum = 3, item = 2 => item = 3, sum = 6
  
   When value of sum is 6, break statement gets executed and iteration gets stopped.
  
   Hence correct option is (C)

(13)
   (a)   Initially i is set to 0.
   (b)   for loop gets iterated from 0 to 10. When the value of i is 10, condition i<10 evaluates to false and the loop iteration gets stopped.
   (c) Value of i after executing the loop is 11.
  
   Hence correct option is (B)

(14)
   (a) Initially variable count is initialized to 0.
   (b)   while loop iterates i from 0 to 10. When i value is 10 the loop gets stopped.
   (c) So the given code prints "Welcome to Java" statement 10 times.

   Hence correct option is (D)

   (b)   while loop iterates i from 1 to 11. When i value is 11 the loop gets stopped.
   (c) So the given code prints "Welcome to Java" statement 10 times.

   Hence correct option is (B)
