Correct option is B
Arguments:I
"The pass percentage in the X standard board exams has declined by 8 percent this year"
This argument supports the statement indirectly because if the pass percentage has dropped, it could be a result of students struggling with questions outside the syllabus. However, this is circumstantial evidence and does not definitively prove that out-of-syllabus questions caused the decline
This Argument is strong because it correlates a decline in pass percentage with possible difficulties caused by out-of-syllabus questions
Argument II:
"The number of students scoring over 60 percent in the X standard board exams has shown an increase of 15 percent this year"
This argument contradicts the statement. If the number of students scoring above 60% increased, it suggests that many students performed well, which makes it less likely that out-of-syllabus questions caused widespread issues. This Argument is weak because it contradicts the claim made by the students
Argument II weakens, while argument I strengthens the statement
Thus, correct answer is (b)
