Answer 2

Answer:

(c) R ⊆ A × B

If R is a relation from set A to set B, then R is always a subset of A × B.

Explanation:

• A relation from A to B is a set of ordered pairs (a, b) such that a ∈ A and b ∈ B.
• In other words, a relation from A to B is a subset of A × B.
• If A is a set then a relation on A means a relation from A to A.
