Mount is the tallest mountain in the world, has provided a challenging adventure for many climbers. a. that b. which c. whom d. who

Mount Everest is not a person, so whom and who cannot be used.

The phrase that the blank spot is in needs a transition word to flow correctly. 'that' does not flow, as it would make this phrase grammatically incorrect.

The answer is B. which.

Replacing the blank with who or whom, would imply that Mount Everest is a person. So, this means both who and whom is incorrect.

Replacing the blank with that would be grammatically incorrect. So, this means the word 'that' would be incorrect.

This leaves us with the remaining option of 'which'.

The word 'which' would be grammatically correct for this sentence.

The final, correct sentence should something like this:

Mount Everest, which is the tallest mountain in the world, has provided a challenging adventure for many climbers.
