Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.940\% 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: COc1ccc(Nc2nc(CC(C)=O)ns2)cc1
b: O=C(NNC(=O)c1cc(-c2ccncc2)nc2ccccc12)c1ccccc1O
c: O=C(CCCN=C1NS(=O)(=O)c2ccccc21)OCc1cc([N+](=O)[O-])cc2c1OCOC2
Answer: a. COc1ccc(Nc2nc(CC(C)=O)ns2)cc1
