Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.467\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(C)cc1NC(=O)NCc1ccc(F)cc1
b: C=CCOC(=O)C1=C[C@H](c2ccc3c(c2)OCO3)C[C@H](OCCCCO)O1
c: COc1ccc(NC(=O)Nc2cccc3ccccc23)cc1OC
d: CCN(CCNCC(O)COCc1ccc(Cl)cc1)c1cccc(C)c1.O=C(O)C(=O)O
Answer: a. COc1ccc(C)cc1NC(=O)NCc1ccc(F)cc1
