Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.556\% 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 CCOC(=O)c1c(NC(=O)C(C)NCc2ccco2)sc2c1CCC(C)C2.O=C(O)C(=O)O
b Cc1ccc2c(CN3CCOCC3)cc(=O)oc2c1C
c COc1ccc(CCNS(=O)(=O)c2ccc(Br)cc2)cc1
Answer: a. CCOC(=O)c1c(NC(=O)C(C)NCc2ccco2)sc2c1CCC(C)C2.O=C(O)C(=O)O
