Problem statement: Answer the multiple choice question.
Query: Which drug has a -4.612\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COC(=O)C1=C(C(=O)OC)C(c2cc(Br)ccc2O)c2sc(=O)[nH]c2S1
b. O=C1N(Cc2cccnc2)C[C@@H]2C[C@@H](c3ccc(-c4ccccc4)cc3)N3CCC[C@@]123
Answer: a. COC(=O)C1=C(C(=O)OC)C(c2cc(Br)ccc2O)c2sc(=O)[nH]c2S1
