Correct option is D
Given:
(1) B is heavier than D but taller than A. → B > D (weight), B > A (height).
(2) A is heavier than B. → A > B (weight).
(3) D and E are shorter than A but heavier than F. → D & E < A (height), D, E > F (weight).
(4) C is shorter than B but taller than F. → F < C < B (height).
(2) A is heavier than B. → A > B (weight).
(3) D and E are shorter than A but heavier than F. → D & E < A (height), D, E > F (weight).
(4) C is shorter than B but taller than F. → F < C < B (height).
Finding the Tallest Boy only:
B > D; D & E < A; B > C > F
From the above inequality, B is tallest one .
Thus, the correct option is (d) B
