Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.299\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOC(=O)/C(C#N)=N/Nc1c(C)n(C)n(-c2ccccc2)c1=O
b. O=C(O)c1ccc(Cl)c(S(=O)(=O)Nc2ccc(OCc3ccccc3)cc2)c1
c. CCc1ccc(NC(=O)COC(=O)CCCC2=NS(=O)(=O)c3ccccc3N2)cc1
Answer: a. CCOC(=O)/C(C#N)=N/Nc1c(C)n(C)n(-c2ccccc2)c1=O
