P. Personiffacion is correct
Correcto Porque hay un pronombre, el imperartivo, y un verbo/accion, comes, y finalmente in adjetivo, mucho.
The name already suggests that the "personal" a is needed for people - So we will choose an option that has a person with its object. (so not with "reglas" )
It's not needed for possession, so it will not appear with the sentences that have "tener" in them.
It is needed in the last option: mira a Pablo.
Also, we will need it for "dile al encargado" because the encargado is a person in charge. But then it will bind with "el" forming "al" - so not "a" anymore
