Task: Answer the multiple choice question.
Query: Which drug has a 11.404\% 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.) CCOc1ccccc1NC(=O)CCNS(=O)(=O)c1ccc(NC(C)=O)cc1
b.) O=C(Nc1ccc(OC(F)F)cc1)c1cc[n+]([O-])cc1
c.) COc1cc(Br)cc(/C=N/NC(=O)Cc2ccccc2)c1O
Answer: b. O=C(Nc1ccc(OC(F)F)cc1)c1cc[n+]([O-])cc1
