Task: Answer the multiple choice question.
Query: Which drug has a 5.226\% 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.) CCC(CO)N=CC1=C(O)CC(c2ccccc2)CC1=O
b.) COc1ccc(S(=O)(=O)N2CCOCC2)cc1NC(=O)c1ccc(Cl)cc1
c.) COc1ccc(S(=O)(=O)N2CCCCC2)cc1NC(=O)c1ccc([N+](=O)[O-])o1
Answer: b. COc1ccc(S(=O)(=O)N2CCOCC2)cc1NC(=O)c1ccc(Cl)cc1
