Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.957\% 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) COc1cc(CCC(=O)OCc2nnc(-c3ccccc3)o2)cc(OC)c1OC
(b) CC(=O)c1coc2c1cc(O)c1ccccc12
(c) O=C(c1ccco1)N1CCN(C(=O)C(c2ccccc2)c2ccccc2)CC1
(d) Cn1c(=O)c2[nH]c(CN3CCN(Cc4ccccc4)CC3)nc2n(C)c1=O
Answer: c. O=C(c1ccco1)N1CCN(C(=O)C(c2ccccc2)c2ccccc2)CC1
