The Correct Option isD
Solution and Explanation
Concept:
Data sufficiency problems test whether the given data is enough to determine the required value.
Explanation:
From Statement I:
B is tallest = 163 cm.
No information about A and C → Not sufficient.
From Statement II:
A is shortest = 154 cm.
No information about B and C → Not sufficient.
Even combining both statements:
We only know tallest and shortest heights.
Height of C is unknown, so total sum cannot be determined.
Hence, data is insufficient.
