الإجابة: C. dynamic variable results within the same day are feature of bronchial asthma.
A peak flow meter is a quick, simple device that patients use at home to follow asthma and exacerbations. Day-to-day (diurnal) variability of PEF is a feature of asthma and supports the diagnosis when spirometry is normal or unavailable. It does not need a PFT lab or a long time (A, B), and it cannot tell obstructive from restrictive disease, which needs spirometry (FEV1/FVC) and lung volumes (D).

The peak flow meter is good for assessing exacerbations and for follow-up at home, so it is not limited to a PFT lab.

A peak flow meter showing daily diurnal variability of PEF (> 10%) is a finding in asthma.

Peak flow is not diagnostic (it is used for acute exacerbations and home follow-up); diagnosis rests on spirometry.
