Task: Answer the multiple choice question.
Question: Which drug has a 4.282% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cn1c(Cc2ccccc2)nnc1SCc1ccc(C(=O)O)cc1
b: CS/C(N)=N/N=C/c1cc(C)ccc1O
c: CN(Cc1ccccc1)c1oc(COc2ccccc2F)nc1C#N
d: Cc1c(C(=O)NC(C)C2CC3CCC2C3)cccc1[N+](=O)[O-]
Answer: b. CS/C(N)=N/N=C/c1cc(C)ccc1O
