What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exist?

developer created this Apex trigger that calls MyClass .myStaticMethod:

trigger myTrigger on Contact (before insert) ( MyClass.myStaticMethod(trigger.new, trigger.oldMap); }

The developer creates a test class with a test method that calls MyClass.mystaticMethod, resulting in 81% overall code coverage.

What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exist?
A . The deployment fails because the Apex trigger has no code coverage.
B . The deployment fails because no assertions were made in the test method.
C . The deployment passes because the Apex code has required (>75%) code coverage.
D . The deployment passes because both classes and the trigger were included in the deployment.

Answer: A
