Task: Answer the MCQ question.
Question: Which drug has a 11.557\% 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(=O)Nc2ccccc2)=C[C@@H](C)[C@@H]1CCCO
b CCN(CC)S(=O)(=O)c1ccc(N2CCCC2)c(NS(=O)(=O)c2ccc(F)cc2)c1
Answer: a. CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](C)[C@@H]1CCCO
