Problem statement: Answer the multiple-choice question.
Question: Which compound has a 1.223\% 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 additional words.
Options:
a: O=C(Cc1coc2ccc3ccccc3c12)Nc1nccs1
b: O=C(NCc1ccccn1)c1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1
c: COC(=O)N/N=C/c1ccc([N+](=O)[O-])o1
Answer: a. O=C(Cc1coc2ccc3ccccc3c12)Nc1nccs1
