Operations On Relations

The correct option is: A, C and D

The correct option is: B and D

Concept: We test options by substitution into compositions. Step 1: {\color{red}Check option (D).} Let: Then: Since: So first condition holds. Step 2: {\color{red}Check second composition.} Now replace structure: Thus condition satisfied structurally. Step 3: {\color{red}Conclusion.} Option (D) fits both compositions.
