Read this sentence.
The temperature in the valley was extremely cold.
The writer revised this sentence to include a metaphor. Which revised sentence includes a metaphor?
The cold made us shake like a leaf.
The valley was a freezer that day.
The valley was cold as an icy tundra.
O The cold nearly pushed us over the edge.

This refers to the figurative expression that is used to show the direct comparison to dissimilar entities in a sentence, without the use of like or as

Hence, we can see that the original sentence stated the temperature at the valley was very cold and this was rewritten and a metaphor added this can be found in option B because the valley was directly called a freezer.

Some more examples of metaphor are:

He was our rock after our dad passed away

She was our pillow whenever we needed comfort, etc.

A direct comparison is done to show how cold the valley was on that day and it was directly compared to a freezer.

This shows the revised sentence to the original sentence that said the valley was extremely cold.

Therefore, the correct answer is option B.
