Task: Answer the multiple-choice question.
Query: Which drug has a 12.626\% 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 other words.
Options:
a: S=C1NCN(Cc2ccco2)CN1c1ccccc1
b: Cc1nn(CCCC(=O)NCCc2ccc(Cl)cc2)c(=O)c2nccn12
c: O=C(O)c1cccc2[nH]c(C(F)(F)F)nc12
d: O=C(O)c1cc(=O)c2ccccc2[nH]1
Answer: d. O=C(O)c1cc(=O)c2ccccc2[nH]1
