Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.933\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(Nc1ccc(Br)cc1)C(c1ccccc1)c1ccccc1
b Cc1cc(-c2ccccc2)nc(=O)[nH]1
c Cc1c(CCC(=O)N2CCC[C@H]2C(=O)O)c(=O)oc2c(C)c3oc4c(c3cc12)CCCC4
Answer: a. O=C(Nc1ccc(Br)cc1)C(c1ccccc1)c1ccccc1
