Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.972\% 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 CN1CCN(Cc2ccc(Br)s2)CC1
b COc1ccc(CN2CCNC(=O)C2CC(=O)NC2CCCCCC2)cc1C
c NC(=O)COC(=O)/C=C/c1cccc(Br)c1
Answer: c. NC(=O)COC(=O)/C=C/c1cccc(Br)c1
