Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.885\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: C#CCN(Cc1ccccc1)S(=O)(=O)C=C
b: CC(NC(=O)Cc1ccsc1)c1ccc(Cl)cc1Cl
c: C=C(C)Cn1c(N2CCN(c3ccc(OC)cc3)CC2)nc2c1c(=O)n(C)c(=O)n2C
d: CC(=O)c1c2c3c(c(Br)ccc3n(C)c1=O)C(=O)c1ccccc1-2
e: COc1ccc(CC(=O)OC(C)CN2CCOCC2)cc1
Answer: b. CC(NC(=O)Cc1ccsc1)c1ccc(Cl)cc1Cl
