Task: Answer the multiple choice question.
Query: Which drug has a 16.324\% 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 COc1cccc(CN(C)C(=O)COc2ccc(C(=O)c3ccc(Cl)cc3)cc2)c1OC
b Cc1c(NC(=O)/C=C/c2cn(-c3ccccc3)nc2-c2ccc(F)cc2)c(=O)n(-c2ccccc2)n1C
c CCOC(=O)CSc1ccc(C(=O)NCCCN2CCOCC2)cc1[N+](=O)[O-]
Answer: a. COc1cccc(CN(C)C(=O)COc2ccc(C(=O)c3ccc(Cl)cc3)cc2)c1OC
