Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.369\% 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: CC(OC(=O)c1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1)C(=O)NC1CCCCC1C
b: COc1ccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)cc1
c: COc1ccc(-c2cn(Cc3ccc(C(N)=O)cc3)c(-c3ccncc3)n2)cc1
Answer: b. COc1ccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)cc1
