Task: Answer the multiple-choice question.
Query: Which drug has a 5.966\% 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. CN(CC(=O)NCc1ccco1)S(=O)(=O)c1ccc(F)cc1
b. O=C(NCCc1ccccn1)c1nc(Cn2ccc([N+](=O)[O-])n2)no1
c. CN(Cc1ccccc1)C(=O)CN1CCCC1=O
d. COc1ccc(OC)c(CC(=O)NC(c2ccccc2)c2ccccc2)c1
Answer: b. O=C(NCCc1ccccn1)c1nc(Cn2ccc([N+](=O)[O-])n2)no1
