Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.747\% 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(NC1CC2CCCC(C1)N2S(=O)(=O)c1ccccc1)c1ccco1
[b] CCC(=O)Nc1ccc(/C(C)=N\NC(=O)c2ccc(C)s2)cc1
Answer: a. O=C(NC1CC2CCCC(C1)N2S(=O)(=O)c1ccccc1)c1ccco1
