Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.396\% 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: CCOC(=O)N1CCN(C(=O)c2ccc3c(c2)N(CC)CCS3)CC1
b: CCOC(=O)C1=C(COC(=O)/C=C/c2cccc(OC)c2)NC(=O)NC1C
c: O=C(NC(=S)N1CCN(C/C=C/c2ccccc2)CC1)c1ccco1
d: Cc1cccc2cc(C#N)c(SCC(=O)Nc3ccccc3N3CCOCC3)nc12
Answer: b. CCOC(=O)C1=C(COC(=O)/C=C/c2cccc(OC)c2)NC(=O)NC1C
