Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.190\% 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) COc1cc(N2CCCC2)c(OC)cc1C=O
b) Cc1csc(SCC(=O)NC2CCC(C)CC2)n1
c) Cc1cc(N2CCCC2=O)ccc1S(=O)(=O)Nc1c(C)nn(C)c1C
Answer: a. COc1cc(N2CCCC2)c(OC)cc1C=O
