Task: Answer the multiple-choice question.
Question: Which compound has a 6.488\% 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: CC(OC(=O)Cn1[nH]c(=O)c2ccccc2c1=O)C(=O)Nc1ccc(Cl)cn1
b: O=Cc1c(C(=O)O)n(CC(=O)O)c2ccccc12
c: Cc1nc2ccccc2c(=O)n1Nc1cccc(Cl)c1
d: Cc1ccc(Cn2c(SCC(=O)N/N=C/c3ccc(C)o3)nc3ccccc32)cc1
Answer: b. O=Cc1c(C(=O)O)n(CC(=O)O)c2ccccc12
