Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.954\% 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)c1sc2ncn(CC(=O)Nc3cc(C)on3)c(=O)c2c1C
b.) O=S1(=O)N=C2CCCN2C(c2ccc(F)cc2)N1
Answer: a. CCOC(=O)c1sc2ncn(CC(=O)Nc3cc(C)on3)c(=O)c2c1C
