Final answer:
Jonathan is using personification when he refers to the heads of his family.
Step-by-step explanation:
The correct answer is personification. When Jonathan repeatedly refers to the heads of his family, he is attributing human qualities (being the leaders) to an inanimate object (the heads). Personification is a figure of speech that gives human characteristics to non-human things. In this case, the heads are being personified as the leaders of the family.
