Step 1: Concept
To determine the shortest, we must establish the relative heights of all three individuals.
Step 2: Analysis of Statement I
Ram > Ravi. Does not mention Raju. Not sufficient.
Step 3: Analysis of Statement II
Raju > Ravi. Does not mention Ram. Not sufficient.
Step 4: Combined Analysis
From I: Ravi is shorter than Ram.
From II: Ravi is shorter than Raju.
Since Ravi is shorter than both Ram and Raju, Ravi is the shortest.
Both statements together are sufficient.
Step 5: Conclusion
Correct answer is (3).
Final Answer: (3)
