Explanation:

In respiratory function tests, a restrictive disorder is typically indicated by a low Forced Vital Capacity (FVC). FEV1% (Forced Expiratory Volume in 1 second as a percentage of FVC) is often normal or high in restrictive disorders (as the air can be exhaled quickly but there's less total volume). FEF25 - 75 (Forced Expiratory Flow between 25% and 75% of FVC) is more related to obstructive disorders (where there is airway narrowing affecting flow during the middle part of exhalation).

Answer:

The low FVC
