Explanation:

To complete the sentence, we need a relative pronoun that refers to Jack Kerouac (a person) and functions as the subject of the relative clause "____ became known as one of the pioneering voices of the Beat Generation". The relative pronoun "who" is used to refer to people and can act as the subject in a relative clause. Other relative pronouns like "which" (for things), "that" (used in restrictive clauses, and here the clause is non - restrictive as it's set off by commas), or "whom" (used as an object) are not appropriate here.
