Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.077\% 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) CCOC(=O)CSc1nnc(SCCN2C(=O)c3ccccc3C2=O)s1
b) O=[N+]([O-])c1cccc(-c2nc3ccccc3s/c2=N/O)c1
Answer: a. CCOC(=O)CSc1nnc(SCCN2C(=O)c3ccccc3C2=O)s1
