Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.064\% 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] CCc1noc(C)c1C(=O)Nc1nc(-c2ccc(OC)cc2OC)cs1
[b] O=C(Nc1cccnc1)c1cc(S(=O)(=O)N2CCCC2)ccc1Cl
[c] Cc1nonc1NC(=O)CSc1nc2ccccc2[nH]1
[d] CCOC(=O)C1(Cc2cccc(F)c2)CCN(Cc2c(C)nn(CC)c2C)CC1
Answer: b. O=C(Nc1cccnc1)c1cc(S(=O)(=O)N2CCCC2)ccc1Cl
