Wait, why is the 'Job' property declared with an arrow function? That's not going to work the way we expect. I think I'll have to go with option A - 'Error: myFather.job is not a function'.

Hmm, the problem seems to be that we're trying to access the 'job' property directly instead of using the 'Job' method on the prototype. I'll go with option D - 'John Developer'.
