Answer:
B. Nero was raised with gentleness and care.
Step-by-step explanation:
Figurative language is a literary device that creates a mental image in the reader through a specific combination of "figurative" and "literal" words that appeal to one's senses (sense of sight, smell, touch or taste).
We can infer that Nero's instructor was "the flower of morality" which is a figurative expression that appeals to our visual sense to explain that he was a moral man that taught him gentle breeding (raised him with gentleness and care).
