To determine the order of marks among B, C, D, F, and H, we arrange them based on the given conditions: 1) Exactly one person scored between C and D. 2) Exactly one person scored between H and D. 3) F scored less than C and D. Placing them in descending order yields: H > C > B > D > F (or B > C > H > D > F depending on position), which consistently leaves 3 people scoring less than B.

Ranking and Ordering puzzles test logical deductions based on linear sequence constraints, which are a standard part of General Mental Ability in competitive exams.
5 individuals total: B, C, D, F, and H.
Order setup places D and F below B, along with one of C or H.
F is strictly established as scoring less than both C and D.
Option A (Two) is incorrect because it ignores the presence of third element below B.
Option B (Three) is correct as exactly three individuals score less than B in the derived sequence.
Option C (One) and Option D (Four) miscalculate the relative rank of B.
B is correct тАФ Exactly three people have scored less than B.
When solving relative ranking questions, align all conditions along a single direction (highest to lowest) to easily count elements below or above any given target.
