Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.467\% 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 additional words.
Options:
[a] Cc1cc(C)c(C)c(S(=O)(=O)NCCN2CCOCC2)c1C
[b] COc1ccc(OCC(=O)Nc2ccncc2)cc1
[c] COc1ccccc1OC(=O)c1cc2ccccc2oc1=O
[d] O=C(Nc1ncccc1O)c1ccc2c(c1)OCCO2
Answer: c. COc1ccccc1OC(=O)c1cc2ccccc2oc1=O
