Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 7.086\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CCO[C@@H]1OC(C(N)=O)=C[C@H](c2coc3ccccc3c2=O)[C@H]1CCCO
b. COc1cccc(CN2CCNC(=O)C2CC(=O)NC2CCOCC2)c1OC
Answer: a. CCO[C@@H]1OC(C(N)=O)=C[C@H](c2coc3ccccc3c2=O)[C@H]1CCCO
