Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -6.140\% 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] CCOCCCNC(=S)N1CCC(NC(=O)C2CCCCC2)CC1
[b] Cc1ccccc1CNC(=O)C(=O)NCC1CCCN1S(=O)(=O)c1ccccc1
[c] CC1CN2C(c3ccc([N+](=O)[O-])cc3)=CSC2=N1
Answer: c. CC1CN2C(c3ccc([N+](=O)[O-])cc3)=CSC2=N1
