Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.897\% 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 COC(=O)[C@@H]1CC[C@@](C)(c2ccc(OC)cc2)C1(C)C
b Cc1ccc(N2C(=S)N(C(=O)c3ccccc3)CC2O)cc1
Answer: a. COC(=O)[C@@H]1CC[C@@](C)(c2ccc(OC)cc2)C1(C)C
