Task: Answer the MCQ question.
Query: Which drug exhibits a 11.553\% 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: Cc1nc2ccc(S(=O)(=O)NCC(=O)N(C)Cc3ccco3)cc2s1
b: COc1cc(/C=C/C(=O)O)cc(OC)c1OC
c: O=[N+]([O-])C(=C1NCCN1)C(Cl)=C(Cl)Cl
Answer: c. O=[N+]([O-])C(=C1NCCN1)C(Cl)=C(Cl)Cl
