Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.686\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(CC(c1ccccc1)c1ccccc1O)NCCN1CCOCC1
(b) CCC1(C(=O)c2ccc(C)cc2)C2c3ccccc3OC(=O)C21C(=O)O
(c) CS(=O)(=O)N1CCC(C(=O)Nc2cccc(Cl)c2Cl)CC1
Answer: c. CS(=O)(=O)N1CCC(C(=O)Nc2cccc(Cl)c2Cl)CC1
