Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.548\% 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 other words.
Options:
a: Nc1nc(CN2CCCCC2)cs1
b: CC(=O)Nc1ccc(NC(=O)COC(=O)Cc2c[nH]c3ccccc23)cc1
c: C/C(N)=C(/C#N)C(=O)CSc1nc2ccccc2c(=O)n1CCCO
Answer: a. Nc1nc(CN2CCCCC2)cs1
