The statement is false because the OPT page-replacement algorithm, the reference bits of all the pages in memory do not have to be reset every clock interrupt.
The OPT algorithm selects the page that will not be used for the longest period of time in the future, based on future memory references. It is not dependent on the current reference bit of the page. Therefore, there is no need to reset the reference bits of all pages in memory.
In fact, the OPT algorithm does not use the reference bits at all. Instead, it requires a prediction of future memory references, which may not be practical in many cases.
