Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.086\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=[N+]([O-])c1ccc(O)c(/C=N/NC2=NS(=O)(=O)c3ccccc32)c1
b O=C1OCC=C1NNC(=O)c1cccnc1
c CCCC(C)C1(CC)C(=O)NC(=Nc2ccccc2)NC1=O
d COC(=O)C1=C(c2cccc(OCc3ccccc3)c2)C[C@@H]2CC[C@H]1N2C(=O)NCc1ccc(OC)c(OC)c1
Answer: b. O=C1OCC=C1NNC(=O)c1cccnc1
