Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.449\% 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: O=[N+]([O-])c1ccc(-c2nnc3n2CCCCC3)cc1
b: COc1cc(-c2nc3ccc(C)cn3c2NCc2ccccc2)ccc1SC1CCCCC1.O=C(O)C(F)(F)F
c: Cc1cc(=O)[nH]c(SCC(=O)N2CCC(C(N)=O)CC2)n1
Answer: a. O=[N+]([O-])c1ccc(-c2nnc3n2CCCCC3)cc1
