To find the total number of students in Sunita's class, we need to add her rank from the top and her rank from the bottom and then subtract 1 (because Sunita herself is counted in both rankings). So, the total number of students in the class = 10 (rank from the top) + 18 (rank from the bottom) - 1 = 27. Therefore, the correct answer is: 4. 27
