Task: Answer the multiple-choice question.
Query: Which compound exhibits a 6.756\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CN(C)c1cccc2c1c(NC(=O)Nc1ccccc1)nn2C
b CC(C)(C)c1ccc(CS(=O)(=O)CC(O)CN2CCCC2=O)cc1
c O=C1C(=O)N(c2ccccn2)C(c2ccc(Br)cc2)/C1=C(/O)c1ccc(Br)cc1
Answer: c. O=C1C(=O)N(c2ccccn2)C(c2ccc(Br)cc2)/C1=C(/O)c1ccc(Br)cc1
