Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.780\% human ether-à-go-go related gene (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. O=C(NNC(=O)c1ccc(Cn2cccn2)o1)NC12CC3CC(CC(C3)C1)C2
b. C=C1CCN([C@@H](CC(C)C)C(=O)Nc2ccc(OC)cc2)S(=O)(=O)c2ccccc21
c. COc1ccc(OC)c(S(=O)(=O)Nc2ccc(OCC(=O)O)cc2)c1
Answer: b. C=C1CCN([C@@H](CC(C)C)C(=O)Nc2ccc(OC)cc2)S(=O)(=O)c2ccccc21
