Answer:
The correct answer is option C) "Famished, Bruce quickly ate his dinner."
Step-by-step explanation:
Formal, standard English avoids de use of informal expressions or idioms.
In option A), the expression "ate like a pig" is very informal and does not use standard English
In option B), "feeling hungry enough to eat a horse" also reflects the use of informal language.
Option C, on the other hand, expresses the idea that Bruce is hungry without any reference to informal language. It only uses the adjective "famished" to describe he was hungry.
