Note: Four possible answers A, B, C and D to each question are given. The choice which you think is correct, fill that circle in front of that question with Marker or Pen ink. Cutting or filling two or more circles will result in zero mark in that question. Write the letter A, B, C or D in the column  (write correct option) against each question also. If there is a contradiction in the bubble and hand written answer, bubble option will be considered correct.
