Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.756\% 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 Cc1ccc(C(=O)N2CCOCC2)cc1S(=O)(=O)N1CCOCC1
b CC(=O)Nc1c(-c2ccc3ccccc3c2)nc2ccccn12
c COc1ccc(-c2c(=O)n(OCc3ccccn3)c3ccccc3[n+]2[O-])cc1OC
d CC1=CN2C(=N)/C(=C/c3ccco3)C(=O)N=C2S1
Answer: d. CC1=CN2C(=N)/C(=C/c3ccco3)C(=O)N=C2S1
