A conjugate acid results when a chemical species receives a hydrogen ion. Moreover, the conjugate base is what is formed after the conjugate acid has been formed. In this case, C5H5N accepts a hydrogen ion, becoming a conjugate acid and the species left over is OH-, making it the conjugate base. Therefore, the answer is B.
