Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.658% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc2[nH]c3ccccc3c2c1
(b) O=C(NCc1ccc(Cl)cc1)C1CCC(CNc2c(N3CCCCC3)c(=O)c2=O)CC1
(c) O=C(/C=C/c1ccc(F)cc1)NC(=S)NNC(=O)[C@H]1C[C@@H]1c1ccccc1
Answer: a. COc1ccc2[nH]c3ccccc3c2c1
