The correct answer is C


Phenylephrine is sympathomimetic vasoconstrictor that has been used as a nasal
decongestant for many years. It is a relatively selective alpha-adrenoceptor agonist. The majority of the sympathomimetic action is due to direct stimulation of the
adrenoceptors and relatively little is due to an indirect effect via release of
noradrenaline.
