Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.715\% 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 other words.
Options:
a) O=c1[nH]c(O)c(C=Nc2ccccc2Oc2ccccc2)c(=O)[nH]1
b) CCc1ccccc1NC(=O)C1=CC(c2ccc(OC)c(OC)c2)=NS(=O)(=O)N1C
c) CS(=O)(=O)O.Cc1ccc(NC(=O)c2ccc(CN3CCN(C)CC3)cc2)cc1Nc1nccc(-c2cccnc2)n1
d) Cc1ccc(-c2csc3nc[nH]c(=O)c23)cc1
Answer: b. CCc1ccccc1NC(=O)C1=CC(c2ccc(OC)c(OC)c2)=NS(=O)(=O)N1C
