Personification is a figure of speech in which human characteristics are attributed to non-human things, such as animals, objects, or abstract concepts. So the answer is (C), a method of working with groups in which the group worker is presented as a model.

Personification can be used to make writing more vivid and engaging, and to help the reader better understand the writer's point of view. For example, instead of saying "The wind was blowing hard," a writer might say "The wind howled like a banshee." This personifies the wind by giving it human qualities, such as the ability to howl.

Personification is also often used in advertising and marketing to make products or services more appealing to consumers. For example, a car advertisement might personify the car by saying that it is "fast and sleek" or "fun to drive." This makes the car seem more like a companion or friend, which can make consumers more likely to want to buy it.

Here are some other examples of personification:

• The sun smiled down on us.
• The flowers danced in the breeze.
• The old house creaked and groaned.
• The river whispered its secrets.
• The city never sleeps.

Personification is a powerful literary device that can be used to create a wide range of effects. It is a common tool used by writers, poets, and advertisers alike.
