Technician A is correct because crankcase vapors are regulated, and an emission monitor system often uses a crankcase pressure sensor to detect whether the filter is plugged or missing. Technician B is incorrect because coalescing filters are designed to separate oil from air and return it to the sump, which should not increase oil consumption.
