Task: Answer the multiple-choice question.
Question: Which drug has a 2.940\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(c1cnccn1)N1CCCC(N2CCN(c3cccc(Cl)c3)CC2)C1
b: O=C(Nc1ccc(-c2nc3ccccc3[nH]2)cc1)c1cccc(N2C(=O)CCC2=O)c1
Answer: a. O=C(c1cnccn1)N1CCCC(N2CCN(c3cccc(Cl)c3)CC2)C1
