Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.462\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(CNc1cccc(S(=O)(=O)N2CCOCC2)c1)Nc1cccc(Br)c1
(b) Cc1ccc(-n2c(SCC(=O)Nc3cccc(S(=O)(=O)NC4=NCCCCC4)c3)nc3ccccc3c2=O)cc1C
(c) CCN1CC2([N+](=O)[O-])CC=C(OC)C([N+](=O)[O-])(C1)C2
Answer: c. CCN1CC2([N+](=O)[O-])CC=C(OC)C([N+](=O)[O-])(C1)C2
