Task: Answer the multiple choice question.
Query: Which compound exhibits a -6.920% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) COC(=O)c1ccc2c(=O)n(CCCCCC(=O)N3CCN(c4ccccc4)CC3)c(=O)[nH]c2c1
b) O=C(Nc1ccncc1)C1COc2ccccc2O1
c) Cc1ccccc1C(=O)N[C@H](C(=O)Nc1ccc(Cl)c(Cl)c1)C(C)C
Answer: b. O=C(Nc1ccncc1)C1COc2ccccc2O1
