Problem statement: Answer the multiple choice question.
Question: Which compound has a -0.931\% human ether-à-go-go related gene (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 Cc1cccc(NC(=O)Nc2ccc(Oc3c(F)c(F)c(F)c(F)c3F)cc2)c1
b O=C(CCNS(=O)(=O)c1ccccc1)NNC(=O)C1COc2ccccc2O1
c CC1(C)OC(=O)N(c2ccccc2)C12C=Cc1cc(Br)ccc1O2
Answer: c. CC1(C)OC(=O)N(c2ccccc2)C12C=Cc1cc(Br)ccc1O2
