Task: Answer the multiple choice question.
Question: Which drug has a 2.822\% 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:

b.) O=C(Cn1cnc([N+](=O)[O-])c1)NCCc1ccccc1
c.) CCOCCCNS(=O)(=O)c1ccc2c(c1)OCCO2
d.) COc1ccc2[nH]c(CN3CCC(CO)(CCOc4ccccc4)CC3)c(C)c2c1
e.) CN(C(=O)Nc1ccccc1)n1cnc2ccccc2c1=O
Answer: b. O=C(Cn1cnc([N+](=O)[O-])c1)NCCc1ccccc1
