Form Label – disabled or enabled?

What is the best practice when it comes to a form having disabled fields? Should we show the associated labels disabled as well?

1) If labels are also disabled then it'll give a stronger clue to the user wherein just by looking at it he/she will know the field is disabled. 2) If the labels are shown enabled and form field shown disabled then user might get an impression that the form hasn't loaded properly.
