What is the function of the relative pronoun in the adjective clause? After the track meet, Lila congratulated the runner to whom she lost the race. A. possessive B. subject C. object of a preposition D. direct object

Hi, the correct answer is C - object of a preposition. It isn't a possessive adjective (that would be for example, your book), it is certainly not a subject, nor is it a direct object, because it has a preposition TO. Thus, this is object of a preposition.
