Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.171\% 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: COc1cccc(NC(=O)CC2(CC(=O)O)CCCC2)c1
b: Cc1ccc(C)c(S(=O)(=O)NCc2ccc(C(=O)N3CCCCC3C)cc2)c1
c: COC(=O)c1cnn2c(C(F)(F)F)cc(-c3ccc(F)cc3)nc12
Answer: c. COC(=O)c1cnn2c(C(F)(F)F)cc(-c3ccc(F)cc3)nc12
