Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 18.687\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=[N+]([O-])c1ccc(-c2noc3cc(C(F)(F)F)cnc23)cc1
b.) COc1ccc(-n2c(SCC(=O)NCc3cccs3)nnc2-c2ccoc2C)cc1
c.) O=C(c1ccc([N+](=O)[O-])s1)N1CCc2ccccc21
Answer: c. O=C(c1ccc([N+](=O)[O-])s1)N1CCc2ccccc21
