AND operation is equivalent to;

- Union
- Intersection
- Both of the above
- Division

Correct answer: 2. Intersection

Explanation: The logical AND operation, often symbolized by the symbol “∩”, is typically used in set theory to denote the intersection of two sets. In other words, it represents the elements that are common to both sets.

For example, let’s consider two sets:

Set A = {1, 2, 3, 4} Set B = {3, 4, 5, 6}

The intersection of sets A and B (denoted by A ∩ B) would be {3, 4}, as these are the elements that appear in both sets.

On the other hand, the logical OR operation (union), typically symbolized by “∪”, represents the combination of elements from both sets.

Using the same sets A and B:

The union of sets A and B (denoted by A ∪ B) would be {1, 2, 3, 4, 5, 6}, as it includes all elements from both sets without repetition.

So, the AND operation is equivalent to the intersection operation, not the union. Therefore, the correct choice is “Intersection.”
