Your Phagocytes Have Transmembrane Proteins Called Toll-Like Receptors (TLR) on Their

Your phagocytes have transmembrane proteins called toll-like receptors (TLR) on their surface, but your mast cells do not because:

A) your phagocytes carry the genetic information to make TLRs but your mast cells do not.
B) your phagocytes run transcription and translation but your mast cells only run transcription.
C) some of your body's cells contain ribosomes but most do not.
D) your phagocytes express some genes that are not expressed in your mast cells (and vice versa) .
