Task: Answer the multiple choice question.
Query: Which drug has a 3.321\% 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 CCn1ccnc1C(O)c1ccc(N(C)C)cc1
b COc1cccc(Cn2c(NCc3ccco3)nc3c2c(=O)n(C)c(=O)n3C)c1
c C/C(=C\C(=O)c1ccc(Cl)cc1Cl)N(C)C
Answer: c. C/C(=C\C(=O)c1ccc(Cl)cc1Cl)N(C)C
