Task: Answer the multiple choice question.
Query: Which compound exhibits a -68.166% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1ccccc1NC(=O)CSC(N)=O
b O=C(Cn1nc(-c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)c2ccccc2c1=O)N1CCCCC1
c CC(=O)NS(=O)(=O)c1ccc(NC(=S)NC(=O)C(C)(C)C)cc1
Answer: b. O=C(Cn1nc(-c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)c2ccccc2c1=O)N1CCCCC1
