Task: Answer the MCQ question.
Question: Which compound has a 9.837\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a CCO[C@H]1OC(C(=O)N2CCOCC2)=C[C@@H](c2coc3ccccc3c2=O)[C@@H]1CCCO
b Cc1[nH]c(C)c(S(=O)(=O)Nc2ccccc2Cl)c1C(=O)N1CCCC1
c COc1ccc(CN(Cc2cccn2C)S(=O)(=O)c2ccccc2)cc1
Answer: a. CCO[C@H]1OC(C(=O)N2CCOCC2)=C[C@@H](c2coc3ccccc3c2=O)[C@@H]1CCCO
