Task: Answer the multiple choice question.
Query: Which compound has a 12.978\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) COC(=O)c1ccccc1NC(=O)c1cccc(COc2ccccc2Cl)c1
b) O=C(/C=C/Nc1ccc(F)c(Cl)c1)c1ccco1
c) O=S(=O)(c1cnc[nH]1)N1CCN(c2ccccc2)CC1
d) O=C(CN1C(=O)c2ccccc2S1(=O)=O)NCCSCc1ccccc1Cl
e) CO.COC(=O)/C=C/c1c(C)[nH]c(=O)[nH]c1=O
Answer: c. O=S(=O)(c1cnc[nH]1)N1CCN(c2ccccc2)CC1
