Task: Answer the multiple choice question.
Query: Which drug exhibits a -17.879% 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, c, or d without using any additional words.
Options:
a.) CN(Cc1nccn1C)C(=O)CC1C(=O)NCCN1CC(c1ccccc1)c1ccccc1
b.) O=C(NC1CC2CCCC(C1)N2Cc1ccccc1)c1cccc(Cl)c1
c.) CC(=O)OCc1c(COC(C)=O)[n+](=O)c2ccccc2n1[O-]
d.) CCc1nc(SCC(=O)Nc2cc(OC)ccc2OC)c2c(C)c(C)sc2n1
Answer: c. CC(=O)OCc1c(COC(C)=O)[n+](=O)c2ccccc2n1[O-]
