Explanation:
Geriatric medicine is a branch of medicine concerned with the prevention of disease or disabilities and the treatment of elderly people or older adults.
First of all, the question asked us to identify the nonmedical professional in the list that can be a part of the geriatric team, and all in the list, except 'a clergy member' are medical professionals, hence the answer.
