In a database management class, students are working on designing a system for data validation using logical operations. They need to implement a boolean operation to ensure certain conditions are met before data is accepted. The system is set up to check two conditions, A and B$,$ for a new user registration:

Condition A: The username must be unique and not already exist in the database.

Condition B: The password must contain a minimum of eight characters.

How will you implement the Validation?

Validation $=$ Condition A AND Condition B

Validation $=$ Condition A OR Condition B

Validation $=$ Condition A XOR Condition B
