This newborn is born prematurely at 28 weeks, so his respiratory distress is not having fully matured lungs.
Fetal lung maturity is indicated when the Lecithin:Sphingomyelin ratio is > 2.0.
Because this newborn is having respiratory distress due to lack of fully matured lungs, it means has decreased lecithin because his Lecithin:Sphingomyelin ratio must be < 2.0.

Lecithin = Dipalmitoylphosphatidylcholine = phosphatidylcholine.
E is incorrect because surfactant protein D is an innate host defense component of surfactant, i.e. it does not function to prevent alveolar collapse.
