Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.951\% 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 NNC(=O)c1cccc(O)c1
b C(#Cc1ccccc1)C[N+]1(CC#Cc2ccccc2)CCCCC1.[Br-]
c COc1ccc(CN(C)Cc2cc(=O)n3ccsc3n2)c(OC)c1OC
d COc1ccc(/C=C/C(=O)OCC(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)cc1OC
e COC(=O)COc1ccc(-c2nn(C)c(=O)c3ccccc23)cc1
Answer: a. NNC(=O)c1cccc(O)c1
