Task: Answer the multiple choice question.
Query: Which drug has a 0.858\% human ether-à-go-go related gene (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: Cc1nnc(SCC(=O)Nc2cc(C(C)(C)C)nn2-c2ccccc2)s1
b: O=C1NC[C@H](Cc2ccc(O)cc2)N(CCc2cccc3ccccc23)C1=O
Answer: b. O=C1NC[C@H](Cc2ccc(O)cc2)N(CCc2cccc3ccccc23)C1=O
