Task: Answer the multiple-choice question.
Question: Which compound exhibits a 9.996\% 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, d, or e without using any other words.
Options:
a: CCC(Cc1ccccc1)NS(=O)(=O)c1c(C)nc2scc(C)n2c1=O
b: O=C(CSc1ncn[nH]1)Nc1ccc(Br)cc1F
c: CC1(C(=O)NCCc2c[nH]c3ccccc23)C=CC2(CCCCC2)N1C(=O)c1ccccc1
d: Cc1ccc2c(CN3CC(C)CC(C)C3)cc(=O)oc2c1
e: CC(=O)c1ccc(S(=O)(=O)NCC2(N3CCOCC3)CCCCC2)cc1
Answer: b. O=C(CSc1ncn[nH]1)Nc1ccc(Br)cc1F
