Task: Answer the multiple choice question.
Question: Which compound has a -2.874% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(COc1ccc(Br)cc1)Nc1ccccc1N1CCCC1
b.) O=C(O)c1ccc(Cl)c(S(=O)(=O)Nc2ccc3cn[nH]c3c2)c1
c.) CC(C)Oc1ccccc1Cn1c(=O)oc2ccccc21
Answer: a. O=C(COc1ccc(Br)cc1)Nc1ccccc1N1CCCC1
