Task: Answer the multiple-choice question.
Question: Which drug has a 2.109\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(Cl)cc1NC(=O)CCS(=O)(=O)c1ccc(C)cc1
b CN1CCN(CC(=O)NN(Cc2ccccc2)c2ccccc2)CC1.O=C(O)C(=O)O
c O=C1/C(=C/c2ccncc2)SC(=S)N1Cc1ccccc1
d CN1CCN(c2nc(NCc3ccco3)nc(N)c2[N+](=O)[O-])CC1
Answer: b. CN1CCN(CC(=O)NN(Cc2ccccc2)c2ccccc2)CC1.O=C(O)C(=O)O
