Step-by-Step Solution

Solution:

The email control requires a non-empty value and a valid email format.
Step 2: Check the value set
'test@example.com' is a valid email and not empty, so both validators pass.
Final Answer:
true -> Option D
Quick Check:
Valid email value = valid control true [OK]

Quick Trick: Valid email string passes required and email validators [OK]

Common Mistakes:

Assuming valid property is false for valid input
Confusing valid with touched or dirty
Expecting null or undefined instead of boolean
