GMAT Sentence Correction (SC) | Re: The new image of Stone Age people as systematic hunters of

In Option E, including should ideally be used to represent the result of previous clause and/or refer back to the main subject - the new image. But in this case it is used to modify tools. Can someone help to understand that part?

Also, as per knowledge 'which' in option D cannot jump over a verb and modify tools. Is that correct?
