Task: Answer the multiple-choice question.
Question: Which drug exhibits a -20.492% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)c1ccc(NC(=O)C(=O)NCc2ccc(/C=C(/C#N)C(=O)NCCOC)o2)cc1
b: O=C(Nc1cccc2ncccc12)C(c1ccccc1)c1ccccc1
c: S=c1[nH]nc(-c2cc(-c3ccccc3)n[nH]2)n1/N=C/c1cccc(Cl)c1
d: COc1ccc(C)cc1S(=O)(=O)N1CCCC(C(=O)N2CCOCC2)C1
Answer: b. O=C(Nc1cccc2ncccc12)C(c1ccccc1)c1ccccc1
