To preserve the value of maxAttempts for the length of the Apex transaction and share its state between trigger executions:

Static Variable:

Static variables are initialized once per transaction and retain their value throughout the transaction.

They can be accessed without instantiating the class.

Private Scope:

Declaring it as private ensures encapsulation and prevents unintended external modification.

Helper Class:

Using a helper class ensures the separation of concerns, keeping trigger logic clean and adhering to best practices.

Example Code:public class HelperClass {

private static Integer maxAttempts = 5; // Default value

public static Integer getMaxAttempts() {

return maxAttempts;

}

public static void setMaxAttempts(Integer attempts) {

maxAttempts = attempts;

}

}

A: Constants (static + final) cannot be modified after initialization.

B: Trigger member variables cannot retain values across executions within the same transaction.

C: Declaring it as a non-static variable in a helper class would reset its value during each trigger execution.

Why Not the Other Options?
