a. doctor and patient
b. friend and enemy
c. mother and father
d. mortal and immortal

The correct answer is A. Doctor and patient

Explanation:

In language, antonyms are words with opposite meanings, for example, big and small. Additionally, antonyms are relational if besides having opposite meanings there is a relationship between the words presented and the meaning of one depends on the other, for example, student/ teacher. This implies, from the options, the pair of words that are relational antonyms are "doctor and patient" because they have an opposite meaning because "doctor" is a professional who treats people with illnesses while "patients" are those being treated. Additionally, these antonyms are "relational" because there is a link or relation between both words and there cannot be a doctor without a patient or vice-versa.
