Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.633\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(NCC#CCOCc1ccccc1)c1ccccc1
b CCOC(=O)COc1c(/C=N\OC)cc(Cl)cc1OC
c NS(=O)(=O)c1ccc(NC(=O)C2COc3ccccc3O2)cc1
d CC(C)(C)NCC(O)COc1ccc(Br)cc1.Cl
Answer: b. CCOC(=O)COc1c(/C=N\OC)cc(Cl)cc1OC
