Correct Answer = C.
<p>  Neuromuscular weakness typically results
     in a normal FRC but decreased TLC and increased RV as the
     respiratory muscles are unable to generate the pleural
     pressure changes necessary to fully inflate/deflate the lung. 
     Obesity results in a low FRC but normal RV and TLC.  Emphysema
     may lead to an increase in all lung volumes depending on its
     severity and certainly should not result in a low TLC.  PE
     will not primarily affect lung volumes but rather may result
     in a low DLCO.
