Task: Answer the multiple choice question.
Query: Which compound has a 2.900\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC1CCC(C(=O)NC(C(=O)NCc2cccnc2)C(C)C)CC1
b: O=S(=O)(c1ccc(Cl)cc1)N1CCN(Cc2c[nH]c3ccccc23)CC1
c: COc1ccc2c(c1)C(C)=CC(C)(C)N2S(=O)(=O)c1ccc(Br)cc1
d: COc1ccccc1OCC(=O)NCCc1nc2ccccc2[nH]1
Answer: b. O=S(=O)(c1ccc(Cl)cc1)N1CCN(Cc2c[nH]c3ccccc23)CC1
