Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.047\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cc1c(OCc2c(Cl)cccc2Cl)c(=O)ccn1-c1ncc(C(F)(F)F)cc1Cl
[b] CN(C)/C=C(/C#N)C(=O)c1cccc(Oc2ccc(C(C)(C)C)cc2)c1
[c] CN1/C(=C\C=N\NC(=O)c2ccccc2Br)C(C)(C)c2ccccc21
[d] Oc1ccc(NCc2ccccc2OCc2ccccc2)cc1
Answer: c. CN1/C(=C\C=N\NC(=O)c2ccccc2Br)C(C)(C)c2ccccc21
