question: Q:A pathologist receives a patient sample for analysis. Cells in the sample are first labeled with fluorescent antibodies and then passed across a laser beam in a single file of particles. The light scatter and fluorescent intensity of the particles are plotted on a graph; this information is used to characterize the sample. This laboratory method would be most useful to establish the diagnosis of a patient with which of the following?? 
  {'A': 'Pancytopenia and deep vein thrombosis with intermittent hemoglobinuria', 'B': 'Ventricular septal defect and facial dysmorphism with low T-lymphocyte count', 'C': 'Multiple opportunistic infections with decreased CD4 counts', 'D': 'Vesicular lesions with dermatomal distribution and dendritic corneal ulcers', 'E': 'Painless generalized lymphadenopathy with monomorphic cells and interspersed benign histiocytes on histology'},
