Lungs Pulmonary Function Test in this COPD patient!

62 YO lady, with COPD is evaluated for chronic dyspnea. She has long history of smoking. RR 30, P 102, afbrile. O/E: cachectic, distant heart sound, increased AP diameter of the chest & expiratory wheezing.
What is the most likely finding on pulmonary function test?

1. Non reversible obstructive pattern with reduced DLco
2. Non reversible obstructive pattern, DLco within normal.
3. Reversible obstructive pattern with normal DLco.
4. Restrictive pattern.
5. FEV1/FVC 90% of the expected.

1. Emphysema
2. Chronic bronchitis
3. Asthma
4. Restrictive lung diseases.
5. Normal, less than 70% is considered significant.

This case looks like Emphysema.

I think its 1. since it is nonreversible unlike asthma since most of elastin tissue damaged and DLCO is decreased. In asthma DLCO increased and its reversible obstructive pattern.
