look at the main structure of choice D:
"[modifier] + a river is the focal point of urban life, BUT the river in San Antonio winds through the middle of the business district and xxxx."
there's no contrast here at all! we have [modifier] + "things are built around rivers" + BUT + "even more things are built around rivers".

there is ambiguity if you eliminate the helping verb.
without the helping verb, there are two interpretations:

you can't tell which of these is the correct meaning without the helping verb; therefore, the helping verb is necessary.

bad idiom: you can't say 'regard X to be Y' (just memorize this)
