Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.627\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) COc1ccc(Cc2nnc(NC(=O)c3ccccc3)s2)cc1OC
b) CCOC(=O)COc1nc2ccc(Br)cc2c(-c2ccccc2)c1C(C)=O
Answer: b. CCOC(=O)COc1nc2ccc(Br)cc2c(-c2ccccc2)c1C(C)=O
