Best answer
Right choice is (a) True

The explanation is: Respirable dust sampling method uses a cyclone to separate and capture dust particles in the range of size. The respirable fraction is attained on a pre-weighed PVC filter which is used for gravimetric analysis. The size of dust particles and its characteristics are obtained by the type of cyclone used with the sampling flow rate.
