Task: Answer the multiple choice question.
Query: Which drug has a 14.227\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) COc1cccc(CN2CCNC(=O)C2CC(=O)NCCn2nc(C)cc2C)c1OC
b.) O=[N+]([O-])c1ccc(N2CCNCC2)cc1Sc1nc2ccccc2[nH]1
c.) O=C(Nc1ccccc1)n1cc(-c2ccccn2)c(N2CCOCC2)n1
Answer: a. COc1cccc(CN2CCNC(=O)C2CC(=O)NCCn2nc(C)cc2C)c1OC
