Explanation:
Option A: we get that A>B>C>D and C>2
Option B: we get A is the largest, C>2, A>4 and every section has a different number of students.
Option C: we get that A>B>C>D, C>2 and A*B*C*D = 10n
Option D: we get A>B>C>D, C>2 and A*B*C*D = 24n
Option E: we get A is the largest, D is the smallest, C>2, A*B*C*D = 24n, and each section has a different number of students.
Statement 9 tells us that each section contributes a different number of students and thus this statement is a must in figuring out each section’s strength.
Thus, options A, C are eliminated. From option B we cannot figure out any value since we don’t have any relation between their values. Hence, option B is eliminated.
Option D tells us about the largest and smallest section, also provides a relation between all their values which can be used to find out possible solutions and also tells us that each section contributes a different number of students which can be used to eliminate the undesirable results.
Thus, option D is the answer
