Hacer una parrillada basically means to have a barbecue in Spanish. Although you didn't write any options here, I managed to find them elsewhere: la nube, el cielo, la cereza, and el fosforo.
La nube is a cloud, el cielo is the sky, la cereza is a cherry, and el fosforo is phosphorus, which is obviously necessary for having a barbecue. Thus the correct answer is el fosforo.
