Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.130\% 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. CCOc1ccc(NC(=O)C2=C(C)C(=O)OC23CCC(C)CC3)cc1
b. O=C(COc1ccc([N+](=O)[O-])cc1)NCc1cccnc1
c. CCCCc1nc2cc(C(=O)N3CCCC(COC)C3)ccc2o1
d. COc1cccc(NC(=O)CC2Oc3ccccc3NC2=O)c1
e. COc1ccccc1NC(=O)C1=C(C)NC2=C(C(=O)CC(c3ccc(OC)c(OC)c3)C2)C1c1coc2ccccc2c1=O
Answer: b. O=C(COc1ccc([N+](=O)[O-])cc1)NCc1cccnc1
