Task: Answer the multiple-choice question.
Question: Which compound exhibits a -2.975\% 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(NCC(O)c1ccccc1)Nc1cccs1
b: CCn1c(-c2ccc(C)cc2)nn(CC(=O)NCCc2ccccc2)c1=S
c: COC(=O)c1ccc(Cn2nc(-c3ccc(C)c(C)c3)ccc2=O)cc1
d: COc1ccc(C(=O)N2CCN(Cc3cc(OC)ccc3OC)CC2)cc1.O=C(O)C(=O)O
Answer: b. CCn1c(-c2ccc(C)cc2)nn(CC(=O)NCCc2ccccc2)c1=S
