Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.501\% 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(C(=O)N2C(=S)NC(=O)/C2=C\c2ccc(C)cc2)cc1
[b] COc1cc(-c2nnc(SCC(=O)c3ccc(C)cc3)o2)cc(OC)c1OC
Answer: a. COc1ccc(C(=O)N2C(=S)NC(=O)/C2=C\c2ccc(C)cc2)cc1
