Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.613% 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 additional words.
Options:
[a] O=C(c1cn(Cc2ccccc2)nc1-c1ccccc1)N1CCN(c2ccccn2)CC1
[b] O=C(Cn1nc(-c2ccccc2)c2ccccc2c1=O)Nc1cccnc1
[c] CCOc1ccc(N2C(=O)CN=C2Nc2ccccc2F)cc1
[d] COc1cccc2c1OC1(C)CC2NC(=O)N1Cc1ccccc1
Answer: b. O=C(Cn1nc(-c2ccccc2)c2ccccc2c1=O)Nc1cccnc1
