Task: Answer the multiple-choice question.
Question: Which drug has a -19.300% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1ccc(S(N)(=O)=O)cc1C(=O)N(C)CC(=O)Nc1ccc(N2CCOCC2)cc1
[b] COc1cc2ccccc2cc1C(=O)Nc1sc2c(c1C(N)=O)CCN(C(C)C)C2.Cl
[c] CCN(CC)CCN1C(=O)C(=O)/C(=C(/O)c2c(C)[nH]c(C(=O)OC)c2C)C1c1ccc(C)o1
[d] O=C(NNC(=O)C1CC1)Nc1ccc(Cl)cc1
Answer: b. COc1cc2ccccc2cc1C(=O)Nc1sc2c(c1C(N)=O)CCN(C(C)C)C2.Cl
