Answer:
The correct answer is option B. killing any sacred animals
Step-by-step explanation:
A gerund phrase is a phrase consisting of a gerund, which is a noun formed by a verb root plus-ing, and any modifiers or objects associated with it. In a sentence, such gerund phrase functions as a noun and can act as a subject or an object.
In the particular sentence shown, The ancient Egyptians avoided killing any sacred animals, the words killing any sacred animals represent a gerund phrase since they fit the characteristics described before, acting in this sentence as an object.
