Answer:
Your answer would be that the figurative language used in the sentence is my father was my rock.
Explanation:
The sentence above contains a metaphor. A metaphor is a figure of speech that makes an implicit, hidden comparison between two things that are unrelated, but which share some characteristics. That is, a comparison of two different objects is made base on a single or some common characteristics. In this case, the speaker compares his/her father to a rock to mean that he/she finds supports in him. He/she believes that his/her father is as strong as a rock.
