Anu has a relation R on the set of her 5 friends defined by 'x is taller than y'. This relation is:

• A. reflexive and transitive
• B. symmetric and transitive
• C. transitive only
• D. equivalence relation

Explanation: No one is taller than themselves → not reflexive. If x is taller than y, y cannot be taller than x → not symmetric. If x > y and y > z then x > z → transitive. So only transitive.
