Task: Answer the multiple-choice question.
Question: Which compound exhibits a -1.641% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1ccc(NC(=O)C2CCN(C(=O)c3ccc(F)cc3)CC2)nc1
b: CCO/C(C)=C1\C(=O)N(CC)c2ccccc21
c: c1ccc(CN=C2NN=C(c3ccccc3)CS2)cc1
d: CC1CN(C(=O)CCc2ccccc2)C(C)CN1C(=O)CCc1ccccc1
e: Cn1c(=O)c2c(ncn2CC(COCc2ccccc2)OCc2ccccc2)n(C)c1=O
Answer: b. CCO/C(C)=C1\C(=O)N(CC)c2ccccc21
