Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.656\% 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 additional words.
Options:
a. CCN(CC(=O)Nc1ccccc1Br)Cc1nc2ccccc2c(=O)[nH]1
b. CC1(OC(=O)c2cccs2)C(=O)C=C2C=C(C3CC3)OC=C2C1=O
c. Cc1ccc(N(C(=O)c2csnn2)C(C(=O)NC2CCCC2)c2cccnc2)c(C)c1
d. Cn1c(N)c(C(=O)COC(=O)C2(c3ccc(Cl)cc3)CCCC2)c(=O)n(C)c1=O
Answer: a. CCN(CC(=O)Nc1ccccc1Br)Cc1nc2ccccc2c(=O)[nH]1
