Usually, we don't throw exception from the testmethods, rather we catch the exception and put them in proper way through assert statement.

like this:

public class MyClass
{
    public String accountId {get;set;}

    public void myMethod()
    {
        if(accountId == null)
        {
            throw new exception ('Account Id is blank');
        }
    }

}

test class to handle exception

public static testmethod void  mytest()
{
    MyClass cls = new MyClass();

    cls.accountId = null;

    try
    {
        cls.myMethod();

    }
    catch (Exception ex)
    {
        if(ex.getMessage().contains('Account Id is blank')
        {
            System.assert(true);    
        }
        else
        {
            System.assert(false);
        }

    }

}

So, it boils down to option D, eliminating all other options as follows:

A) Throwing a customer exception in the unit test - This cannot be good option

B) Assert that a null value is accepted by the method - This is not a testing negative scenario

C) Asert that past dates are accepted by the method - This is positive test

D) Assert that future dates are rejected by the method - This is correct way for doing negative test.
