Task: Answer the multiple-choice question.
Query: Which drug has a 4.755\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CC(CCc1ccco1)NC(=O)CCc1nnc2ccc(NCc3ccccc3Cl)nn12
(b) OC[C@H]1O[C@@H](Oc2ccc3cc(Br)ccc3c2)[C@H](O)[C@@H](O)[C@H]1O
(c) CN(C(=S)Nc1ccccc1F)C1(c2ccccc2Cl)CCCCC1=O
(d) COc1ccc(C(CNC(=O)c2cccc(N(C)C)c2)N2CCCC2)cc1
Answer: b. OC[C@H]1O[C@@H](Oc2ccc3cc(Br)ccc3c2)[C@H](O)[C@@H](O)[C@H]1O
