To solve this question, we need to analyze the given information step by step.

1. Set up the seating arrangement:
- Let's represent the persons as A, B, C, D, and E from left to right.
- According to the given information, the sharp person and the fair person are at the farthest ends. So, A and E are sharp and fair, but their positions are not known yet.
- An overweight person is sitting to the right of a feeble person. Let's assume that C is overweight, and D is feeble.
- A tall person is to the left of the fair person. Let's assume that B is tall.

2. Determine the positions of the sharp and fair persons:
- The feeble person (D) is sitting between the sharp (A) and overweight (C) persons. So, the seating arrangement is either ADBCE or ADEBC.

3. Find the position of David:
- David ranks 7th from the top and 28th from the bottom. Since there are no other given constraints, we can assume that David is sitting at a fixed position.
- In the seating arrangement ADBCE, David is sitting at the 7th position from the top. So, the arrangement becomes ADBCE(David).
- In the seating arrangement ADEBC, David is sitting at the 28th position from the bottom. So, the arrangement becomes (David)ADEBC.

4. Determine the number of students in the class:
- Since David is sitting in both arrangements, the number of students in the class must be the same in both cases.
- In both arrangements, David's position is fixed, and there are 6 persons in the arrangement before David.
- From the top, there are 6 students above David, and from the bottom, there are 27 students below David.
- So, the total number of students in the class is 6 + 1 + 27 = 34.

Therefore, the correct answer is option C) 34.
