Task: Answer the multiple-choice question.
Question: Which compound exhibits a 4.520\% 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) Cc1cc(Br)c(NC(=O)c2ccccc2[N+](=O)[O-])cc1C
(b) Cc1cc(C)c(-n2c(C)cc(/C=C3/NC(=O)NC3=O)c2C)c(C)c1
(c) O=C(N/N=C/C1C(c2ccccc2)C1(Cl)Cl)c1cccc(Br)c1
Answer: a. Cc1cc(Br)c(NC(=O)c2ccccc2[N+](=O)[O-])cc1C
