Solve the following python programming problem given the following code:
@ pytest.mark.django_db 
def test_get_dependencies(monkeypatch) : 
    compiler = compilers.BaseCompiler () 
    assert (models.Dependency.objects.exists () is False) 
    assert (compiler.get_dependencies ('spam.scss') == []) 
    dependency_1 = models.Dependency.objects.create (source = 'spam.scss', depends_on = 'ham.scss') 
    dependency_2 = models.Dependency.objects.create (source = 'spam.scss', depends_on = 'eggs.scss') 
    def get_full_source_path(source_path) : 
        if (source_path == 'eggs.scss') : 
            raise ValueError () 
return source_path 
monkeypatch.setattr (compiler, 'get_full_source_path', <MASK>) 
    assert (list (models.Dependency.objects.all ()) == [dependency_1, dependency_2]) 
    assert (compiler.get_dependencies ('spam.scss') == ['ham.scss']) 
    assert (list (models.Dependency.objects.all ()) == [dependency_1]) 
    
    Given the code above, what is a proper replacement for <MASK>? Choose among: monkeypatch, compiler, dependency_1, dependency_2
