Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.642% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C1C(=O)N(CCN2CCOCC2)C(c2cccnc2)/C1=C(/O)c1ccc(Cl)cc1
b) Cn1c(OCc2cccnc2)nc2c1c(=O)n(Cc1ccc(F)cc1)c(=O)n2C
Answer: a. O=C1C(=O)N(CCN2CCOCC2)C(c2cccnc2)/C1=C(/O)c1ccc(Cl)cc1
