Task: Answer the multiple choice question.
Query: Which compound exhibits a -4.069\% 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 additional words.
Options:
a. O=C(CO/N=C/c1ccc(OC(F)F)cc1)NCc1ccco1
b. O=C(CSc1nc2ccccc2n1CC(=O)N1CCCC1)Nc1nccs1
c. CC(=O)c1sc2nc(SCC(=O)NCCc3ccccc3)[nH]c(=O)c2c1C
Answer: a. O=C(CO/N=C/c1ccc(OC(F)F)cc1)NCc1ccco1
