In a Tester, which operator connects two clauses to require both conditions?

• A. Or
• B. And Not
• C. And
• D. Or Not

Answer: (C)

Using the And operator creates a logical conjunction between two clauses, so the test passes only when both conditions are true. This is exactly what it means to require both conditions: neither clause can be false, and both must hold for the overall result to be true. For example, checking that a value is greater than 50 AND less than 100 ensures the value lies in that inclusive range, only passing if both comparisons are satisfied. Other operators don’t enforce that all conditions be true. Or would pass if either condition is true, which defeats the requirement to have both. And Not combines a condition with the negation of another (for instance, A AND NOT B), which is not the same as simply requiring both positive conditions. Or Not is similar to Or but with a negation, again not the same as requiring both conditions to be true.
