Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.280% 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 other words.
Options:
a) CN(C)P(=NC(=O)COc1ccc(Cl)cc1Cl)(N(C)C)N(C)C
b) Fc1ccc(-c2nnc(SCc3cccnc3)o2)cc1
c) CC(=O)N1C(=O)C2(Nc3ccccc3N2)c2ccccc21
d) O=C(C1=C[C@@H](c2coc3ccccc3c2=O)C[C@@H](OCCCCO)O1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
Answer: c. CC(=O)N1C(=O)C2(Nc3ccccc3N2)c2ccccc21
