Task: Answer the multiple-choice question.
Query: Which compound exhibits a 3.493\% 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, c, or d without using any other words.
Options:
a. O=C(COc1ccccc1)Nc1ccc(CSc2ccccc2)cc1
b. CC1CCN(CCOc2ccc(C(=O)c3ccccc3)cc2)CC1.O=C(O)C(=O)O
c. Cc1ccc(S(=O)(=O)/N=C2/NC(=O)/C(=C\c3cc(Br)cc(Br)c3O)S2)cc1
d. CCOC(=O)N1CCN(C(=O)CSCC(=O)Nc2nc(-c3ccc(OC)cc3)cs2)CC1
Answer: b. CC1CCN(CCOc2ccc(C(=O)c3ccccc3)cc2)CC1.O=C(O)C(=O)O
