Task: Answer the multiple-choice question.
Question: Which drug has a 11.844\% 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. COc1ccc(C(=O)/C(=C/N(C)C)S(=O)(=O)c2ccccc2)cc1
b. CC(C)CN(C(=O)c1cccc(F)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
c. O=C(Oc1cccc(NC(=O)c2ccco2)c1)c1cccc(S(=O)(=O)N2CCCC2)c1
d. O=C(OCC(=O)N1CCOCC1)c1ccc(Cl)cc1[N+](=O)[O-]
Answer: d. O=C(OCC(=O)N1CCOCC1)c1ccc(Cl)cc1[N+](=O)[O-]
