Task: Answer the multiple-choice question.
Query: Which compound exhibits a 19.973\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(CSCCO)Nc1ccccc1
b: O=C(CSc1ccccc1)Nc1nnc(C2CC2)s1
c: Cc1cc(C)cc(N=c2c([N+](=O)[O-])nn(-c3ccc(Cl)cc3)n2O)c1
d: Cc1[nH]n(C(N)=S)c(=O)c1N=Nc1cccc(Cl)c1
e: CC(NC(=O)CCCc1nnc2n(C)c(=O)c3sccc3n12)c1ccccc1
Answer: c. Cc1cc(C)cc(N=c2c([N+](=O)[O-])nn(-c3ccc(Cl)cc3)n2O)c1
