Explanation:

Let’s check each option for the highest success rate in the annual exam:

- Success rate in annual exam = (Number of students who passed annual exam) / (Total students in section) × 100

- Students who passed the annual = Passed in both exams + Failed in half-yearly but passed in annual

Section A:

- Passed annual = 64 (passed both) + 14 (failed half-yearly, passed annual) = 78

- Total = 28 + 14 + 6 + 64 = 112

- Success rate = 78 / 112 × 100 ˜ 69.64%

Section B:

- Passed annual = 55 + 12 = 67

- Total = 23 + 12 + 17 + 55 = 107

- Success rate = 67 / 107 × 100 ˜ 62.62%

Section C:

- Passed annual = 46 + 8 = 54

- Total = 17 + 8 + 9 + 46 = 80

- Success rate = 54 / 80 × 100 = 67.5%

Section D:

- Passed annual = 76 + 13 = 89

- Total = 27 + 13 + 15 + 76 = 131

- Success rate = 89 / 131 × 100 ˜ 67.94%

- Comparing all, Section A: 69.64%, B: 62.62%, C: 67.5%, D: 67.94%

- Section A has the maximum success rate.

- So, the correct answer is option 1 – A.

- Option 1 is correct.
