Task: Answer the multiple choice question.
Question: Which drug exhibits a -22.846\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COc1ccc(C2N3CC4(C)CN2CC(C)(C3)C4)cc1OC
b) CCOc1cc(/C=C/c2cc(C(F)(F)F)[nH]c(=O)n2)ccc1O
c) Cl.O=C(CCN1CCC(c2ccccc2)C1)c1ccccc1
Answer: c. Cl.O=C(CCN1CCC(c2ccccc2)C1)c1ccccc1
