Task: Answer the multiple choice question.
Question: Which drug has a 3.912\% 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: NC(=S)N=Nc1ccc(NN=C(N)N)cc1
b: CSc1ccccc1NC(=O)c1c(Br)cnn1C
c: Cc1ccc(C(=O)N2CCOCC2)cc1Cl
d: Cc1cc2cc(CN(CC3CCCO3)C(=S)Nc3ccccc3)c(=O)[nH]c2cc1C
Answer: b. CSc1ccccc1NC(=O)c1c(Br)cnn1C
