Task: Answer the multiple-choice question.
Query: Which compound exhibits a -3.628\% 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 additional words.
Options:
[a] O=C(CNC(=S)NC(=O)c1cccs1)c1ccccc1
[b] NS(=O)(=O)c1ccc(N/N=C2/CCCCC2C2CCCCC2)c([N+](=O)[O-])c1
[c] CS(=O)(=O)N1CCN(c2ccccc2NC(=O)c2cccnc2)CC1
Answer: c. CS(=O)(=O)N1CCN(c2ccccc2NC(=O)c2cccnc2)CC1
