1. Correct Answer: Option B: Test II
 2. Explanation:
     To determine in which test the student's performance is the best comparatively, we need to consider how the score of 74 compares to the average and the range of marks for each test.
     ● Test I:  
           ○ *Average Marks*: 60
           ○ *Range of Marks*: 30 to 90
           ○ *Comparison*: The score of 74 is 14 marks above the average (74 - 60 = 14).
     ● Test II:  
           ○ *Average Marks*: 60
           ○ *Range of Marks*: 45 to 75
           ○ *Comparison*: The score of 74 is 14 marks above the average (74 - 60 = 14). However, since the maximum score is 75, scoring 74 is very close to the top of the range.
     ● Test III:  
           ○ *Average Marks*: 70
           ○ *Range of Marks*: 20 to 100
           ○ *Comparison*: The score of 74 is 4 marks above the average (74 - 70 = 4).
     ● Test IV:  
           ○ *Average Marks*: 80
           ○ *Range of Marks*: 0 to 100
           ○ *Comparison*: The score of 74 is 6 marks below the average (74 - 80 = -6).
     Conclusion: The student's score of 74 is closest to the maximum score in Test II and is significantly above the average, making it the best comparative performance.
