Task: Answer the multiple choice question.
Question: Which drug has a 13.975\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(CSc1n[nH]c(=O)[nH]c1=O)Nc1ccc(Br)cc1Br
b: O=C(/C=C/c1ccc(Cl)cc1)N1CCN(c2ccc(Cl)cc2[N+](=O)[O-])CC1
c: c1ccc2[nH]c(CN3CCOCC3)nc2c1
Answer: c. c1ccc2[nH]c(CN3CCOCC3)nc2c1
