Statements:
(I) B is taller than only A.
(II) D is shorter than only C.
Who is tallest among the persons A, B, C and D?
Statements:
(I) B is taller than only A.
(II) D is shorter than only C.
Show Hint
“Shorter than only one person” means that person is the second tallest.
“ Taller than only one person” means that person is the second shortest.

- Statement (I) alone is sufficient to answer the question, but (II) alone is not sufficient.
- Statement (II) alone is sufficient to answer the question, but (I) alone is not sufficient.
- Both the statements (I) and (II) are sufficient to answer the question, but neither statement alone is sufficient.
- Both the statements (I) and (II) together are not sufficient to answer the question and additional data are required.

The Correct Option is B
Solution and Explanation
Concept:
To determine the tallest person, we need enough comparison information among all persons.
Ranking statements like “taller than only” or “shorter than only” help establish relative order.
Step 1: Checking Statement (I).
Given: B is taller than only A. This means: \[ A < B \] and B is shorter than the remaining two persons. So possible order: \[ A < B < C,D \] But we cannot determine whether C or D is tallest. Thus, Statement (I) alone is not sufficient.
Step 2: Checking Statement (II).
Given: D is shorter than only C. This means D is taller than A and B but shorter than C. So the order becomes: \[ A,B < D < C \] Thus, C is definitely tallest. Hence, Statement (II) alone is sufficient. So, the correct answer is (B).
Step 1: Checking Statement (I).
Given: B is taller than only A. This means: \[ A < B \] and B is shorter than the remaining two persons. So possible order: \[ A < B < C,D \] But we cannot determine whether C or D is tallest. Thus, Statement (I) alone is not sufficient.
Step 2: Checking Statement (II).
Given: D is shorter than only C. This means D is taller than A and B but shorter than C. So the order becomes: \[ A,B < D < C \] Thus, C is definitely tallest. Hence, Statement (II) alone is sufficient. So, the correct answer is (B).
