Task: Answer the multiple choice question.
Query: Which drug has a 12.866\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CC(=O)Nc1ccc(-n2c(C)ccc2C)cc1
b. Cc1c(Br)ccc(NC(=O)c2ccccc2[N+](=O)[O-])c1C
c. COc1ccc(N2CC(C(=O)NCCC3=CCCCC3)CC2=O)cc1
Answer: a. CC(=O)Nc1ccc(-n2c(C)ccc2C)cc1
