Task: Answer the multiple choice question.
Question: Which drug has a 2.846\% 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 additional words.
Options:
(a) C=C(Cl)COC(=O)[C@H]1C2C=CC(C2)C1C(=O)O
(b) CCOC(=O)Cc1nnc(NC(=O)C(CC)Sc2nc(C)cc(=O)[nH]2)s1
(c) COc1ccc(NC(=O)Nc2nnc(N3CCC(C)CC3)s2)cc1OC
Answer: a. C=C(Cl)COC(=O)[C@H]1C2C=CC(C2)C1C(=O)O
