Task: Answer the multiple-choice question.
Query: Which compound has a 5.348\% 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 additional words.
Options:
a O=C(CSc1ncccn1)NN=C1CCCCCC1
b O=C(Nc1ccccc1)O/N=C(\c1ccccc1)c1ccccn1
c Cc1cccc(NC(=O)CCNC(=O)c2ccc(Br)cc2)c1C
d O=C(Nc1nc2c(F)cc(F)cc2s1)C1COc2ccccc2O1
Answer: b. O=C(Nc1ccccc1)O/N=C(\c1ccccc1)c1ccccn1
