The correct answer is metaphor. Passing the torch is a metaphor which means that you are passing on some traditions or knowledge to someone else. It can't be an allusion because allusion is a reference to something outside of the text; simile is comparison using words such as like or as; personification is when non-human entities or objects have human characteristics.
He is correct on that one. A metaphor is like another way of saying something, but the way you say it is not literal. Like in this example, Looking for my keys is like finding a needle in a hay stack. It is saying that is is really hard to find something. Any type of saying like it snowed over or it's a piece of cake, those are metaphor. So yes the answer is a metaphor.
