Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.055\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccccc1C(=O)Nc1ccc(C(=O)Nc2ccccc2C(=O)O)cc1
b: CCC(=O)N(Cc1cc(=O)[nH]c2ccccc12)c1ccc(C)cc1
c: CCN1C(=NCc2ccccc2)N[C@@H](c2ccccc2)[C@H](C(=O)OC)[C@H]1C
Answer: b. CCC(=O)N(Cc1cc(=O)[nH]c2ccccc12)c1ccc(C)cc1
