Reliability refers to the consistency of measurement over time, so Dr. Riviera is trying to establish whether his quiz results are consistent from week to week. Validity refers to whether a test actually measures what it is supposed to measure, which is not the main concern Dr. Riviera is addressing in this scenario. Objectivity refers to the lack of bias in the measurement process and subjectivity refers to personal opinions and values, neither of which is relevant to this scenario.
