Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.397\% 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] COc1ccc(C(=O)CC(=O)O)c2c1C=CC(C)(C)O2
[b] CCSc1nnc(-c2ccc(S(=O)(=O)N3CCCC3)cc2)n1C
Answer: a. COc1ccc(C(=O)CC(=O)O)c2c1C=CC(C)(C)O2
