Объяснение:
если есть предлог "since", то используется время Present Perfect Continuous; если есть предлог "by", то нужен пассивный залог, и время здесь простое прошедшее, потому что это однократное действие; в третьем там нужен пассивный залог, потому что ужин не может сам себя приготовить, остальные формы грамматически неправильны.
