To identify the valid equivalence values if the student clears the exam, we need to consider the minimum passing score of 24 marks and the maximum score of 40 marks.
The valid equivalence values would be any score that is equal to or higher than the minimum passing score, but not exceeding the maximum score.
Let's go through each option to determine which one contains the valid equivalence values:
Option A) 22,23,26 - None of these values meet the condition of being equal to or higher than 24 marks.
Option B) 21,39,40 - 39 and 40 are higher than the minimum passing score of 24, but 21 is below the minimum passing score.
Option C) 29,30,31 - All of these values meet the condition of being equal to or higher than 24 marks, but not exceeding 40 marks.
Option D) 0,15,22 - None of these values meet the condition of being equal to or higher than 24 marks.
Therefore, the correct answer is option C) 29,30,31. These values are valid equivalence values as they are equal to or higher than the minimum passing score of 24 marks and do not exceed the maximum score of 40 marks.
