الإجابة: B. Normal FEV1/FVC ratio, reduced FEV1, reduced FVC equally
Interstitial lung disease (here linked to RA/methotrexate) is a restrictive disease: FEV1 and FVC both fall, so the FEV1/FVC ratio stays normal. A reduced ratio (C) indicates obstruction.

A low FEV1/FVC ratio (FEV1 lowered more than FVC) is the obstructive pattern, not the restrictive pattern of ILD.
