Task: Answer the multiple-choice question.
Query: Which drug has a 22.918% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(NCCO)c1nc2ccccc2s1
b: CCCC[C@@H]1CN=C(N)N1CCCC
c: CC(=O)c1c(C(C)=O)c(C)n(-c2nc(-c3ccc(C)c(C)c3)c(C)s2)c1C
Answer: b. CCCC[C@@H]1CN=C(N)N1CCCC
