Explanation

Prostacyclin or PGI2 is a prostaglandin member of the family of lipid molecules known as eicosanoids. It inhibits platelet activation and is also an effective vasodilator agent.Dopamine or 3,4-dihydroxyphenethylamine is a neurotransmitter in the catecholamine and phenethylamine families that plays a number of important roles in the brains and bodies of animals.Argipressin is also known as vasopressin or antidiuretic hormone (ADH), is a neurohypophysial hormone found in most mammals. Its two primary functions are to retain water in the body and to constrict blood vessels.Pyridoxal is one of the three natural forms of vitamin B6, along with pyridoxamine and pyridoxine (also called as pyridoxol). All of these forms are converted in the human body into a single biologically active form, pyridoxal 5-phosphate. Green plants are a natural source of pyridoxal, and its deficiency in the human body leads to serious complications such as epilepsy and seizures. Hence, the correct sequence of the codes is A-5, B-3, C-1, D-2.
