Task: Answer the multiple choice question.
Query: Which drug has a 12.555\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCOC(=O)c1c(CC(C)C)csc1NC(=O)COC(=O)C1=NNC(=O)CC1
b) COCCNC(=O)C1CCC(CNS(=O)(=O)c2c(C)cc(C)cc2C)CC1
Answer: a. CCOC(=O)c1c(CC(C)C)csc1NC(=O)COC(=O)C1=NNC(=O)CC1
