Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.838\% 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) C=CCC12C=C(OC)C(=O)OC(OC)(C1O)[C@H](c1ccc3c(c1)OCO3)[C@H]2C
(b) CC1(C)CC2(CCO1)N1CC3(C)CN2CC(C)(C1)C3O
(c) C[C@@H]1C[C@@H]2O[C@H]2/C=C\C=C\C(=O)Cc2c(Cl)c(O)cc(O)c2C(=O)O1
Answer: a. C=CCC12C=C(OC)C(=O)OC(OC)(C1O)[C@H](c1ccc3c(c1)OCO3)[C@H]2C
