Task: Answer the multiple choice question.
Query: Which drug has a 13.256\% 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) O=C(CCc1c[nH]c2ccccc12)N[C@@H](Cc1c[nH]c2ccc(O)cc12)C(=O)O
(b) CSc1cccc(NC(=S)N2CCCN(Cc3ccc(F)cc3)C2)c1
Answer: a. O=C(CCc1c[nH]c2ccccc12)N[C@@H](Cc1c[nH]c2ccc(O)cc12)C(=O)O
