The symptoms suggest damage to a cranial nerve responsible for eye movement and reflexes. The goal is to determine which cranial nerve is affected. In this case, the inability to adduct, depress, and elevate the right eye, along with the absence of a pupillary light reflex, indicates damage to cranial nerve III (oculomotor nerve), which is responsible for most eye movements and pupillary constriction. However, since cranial nerve VI (abducens nerve) is responsible for lateral eye movement and could be implicated in the adduction issue, the correct answer is cranial nerve VI."}
