Answer:
Personification
Step-by-step explanation:
Personification is a figure of speech where we give human characteristics to inanimate objects.
In the given example we have Butterkist which is a famous British company that produces, among other food, biscuits. The sentence gives us an impression like Butterkist is a real person, a cook, who cooks those biscuits, so in a way, we gave life to the company and that represents personification.
