Task: Answer the multiple-choice question.
Question: Which drug has a 8.195\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) c1ccc(SCc2nc(-c3ccncc3)no2)cc1
b.) CCc1nc2c(nnn2Cc2ccc(F)cc2)c(=O)[nH]1
c.) O=C(Nc1ccc([N+](=O)[O-])cc1)N1CCN(C(=O)C2CCCO2)CC1
d.) O=C(Nc1ccc(Cl)cc1)Nc1ccc(Br)cn1
Answer: d. O=C(Nc1ccc(Cl)cc1)Nc1ccc(Br)cn1
