Problem statement: Answer the multiple choice question.
Query: Which drug has a 19.476\% 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: O=C(Nc1cccnc1)c1ccccc1NS(=O)(=O)c1ccc(F)cc1
b: Cc1cc(C)c(OCC(=O)OCC(=O)NNC(=O)c2ccccc2F)c(C)c1
c: Clc1ccc2[nH]cc(-c3nnnn3-c3ccc4ccccc4c3)c2c1
Answer: c. Clc1ccc2[nH]cc(-c3nnnn3-c3ccc4ccccc4c3)c2c1
