In the first readers-writers problem, a writer may starve if a continuous series of readers arrive before the earlier readers exit their critical section. This is because in the first version, once a writer requests access, it must wait until all currently executing readers complete their critical section before being given access. Therefore, if a continuous series of readers arrive, the writer will be continually blocked and may starve. In the second version, there is no starvation for either readers or writers, so option B and D are incorrect. Option C is also incorrect as it refers to a scenario that is not present in either version of the problem.
