Problem statement: Answer the multiple choice question.
Question: Which compound has a 15.299\% 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] O=C(Nc1nc(-c2cccc([N+](=O)[O-])c2)cs1)C(c1ccccc1)c1ccccc1
[b] CCO.N#Cc1c(SC(C(=O)O)c2ccccc2)nc2c(c1-c1cccs1)CCCC2
[c] O=c1nc(NC2CCCC2)ccn1Cc1cccc(Br)c1
Answer: a. O=C(Nc1nc(-c2cccc([N+](=O)[O-])c2)cs1)C(c1ccccc1)c1ccccc1
