MCQ
Let R be a relation from a set A to a set B, then:
- A$\text{R}=\text{A}\cup\text{B}$
- B$\text{R}=\text{A}\cap\text{B}$
- ✓$\text{R}\subseteq\text{A}\times\text{B}$
- D$\text{R}\subseteq\text{B}\times\text{A}$
✓
Answer
Correct option: C.
$\text{R}\subseteq\text{A}\times\text{B}$
If R is a relation from set A to set B, then R is always a subset of A × B.
