Unlike psychiatrists, who are trained as medical doctors, psychologists have historically been forbidden from prescribing their patients drugs, but in 2002 New Mexico began to grant the privilege of prescribing to licensed, doctoral level psychologists who complete an additional training and certification program.

看一下Ron的解释:
* "forbid ... to" is more or less universally preferred to "forbid ... from" in formal written english, so i would assume that the gmat will follow the same preference.
a couple of other points:
* "prescribe drugs for their patients" is much better than "prescribe their patients drugs" (which would be fine in spoken language, but is at best awkward and at worst ambiguous when written)
* "prescribing privileges" is better than "the privilege to prescribe / privilege of prescribing", especially if the latter is placed at the end of the underlined part (as it is in choice a). the problem with the wording in choices (a) and (d) is that it's ambiguous: "...the privilege of prescribing to ... psychologists" could be taken to mean that the prescriptions themselves are being written for psychologists.
