The answer is A, and there are 7 persons with the right answer, but we shall be rewarding only Clement and Ella. Details below:
Pseudoephedrine and ephedrine are sympathomimetic agents that stimulate
alpha- and beta-adrenergic receptors in the sympathetic nervous system,
causing constriction of smooth muscles and blood vessels and producing
bronchodilatation. They have central nervous system stimulant activity. Pseudoephedrine is a stereoisomer of ephedrine and it is present as a nasal decongestant in a number of cold and cough preparations, such as Day Nurse.
