Task: Answer the multiple choice question.
Query: Which drug has a 18.386\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] C=CCN([C@@H](CC(C)C)C(=O)OC)S(=O)(=O)N(CC=C)[C@@H](CC(C)C)C(=O)OC
[b] c1ccc(Cc2nnc3sc(-c4ccccn4)nn23)cc1
[c] CC1(C)O[C@H]2CC(=O)OC[C@@]23C1CC(=O)[C@]1(C)C3CC[C@@]2(C)[C@H](c3ccoc3)OC(=O)[C@H]3O[C@]321
Answer: a. C=CCN([C@@H](CC(C)C)C(=O)OC)S(=O)(=O)N(CC=C)[C@@H](CC(C)C)C(=O)OC
