Lungs Pulmonary lavage after three days of smoking!

A 19-year-old, otherwise healthy non-smoker designs an experiment to understand the lung’s immunological response to smoking. The experiment entails that he smoke 10 cigarettes per day for 3 days. At the end of 3 days, pulmonary lavage will be expected to show:
A. Neutral pink cells when stained by hematoxylin
B. Dark blue cells when stained by hematoxylin
C. Increased monocytes and lymphocytes
D. Bright red cells when stained by hematoxylin.
E. Increased type II pneumocytes

A

Acute inflammation; and the most prominent cells during the first day is Neutrophils.

Whereas basophilic white blood cells stain dark blue and eosinophilic white blood cells stain bright red, neutrophils stain a neutral pink.

I think smokers have increased neutrophile in their lung . . .
So dark bule stained cell would be the answer rather than pink cell. .
