Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.154% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CSc1nc(-c2ccc(N(C)C)cc2)c(C#N)c(=O)n1C
b CC(=O)C1=C(C)N(CC2CC2)C(=O)N[C@H]1c1ccc(Br)cc1
c CCCn1cc(S(=O)(=O)CC(=O)NC2CCCCC2)c2ccccc21
d CCN(Cc1ccccc1)C(=O)Cn1c(=O)oc2ccccc21
Answer: b. CC(=O)C1=C(C)N(CC2CC2)C(=O)N[C@H]1c1ccc(Br)cc1
