Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 6.221\% 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 other words.
Options:
a: CC(NC(=O)c1ccccc1)c1nnc(SCC(=O)NC2=NCCS2)n1C
b: CCc1ccc(-c2cc(C)no2)cc1S(=O)(=O)Nc1cc(C)ccn1
c: O=C(CCl)NCCCN(C(=O)C(Cl)Cl)c1ccc([N+](=O)[O-])cc1
Answer: c. O=C(CCl)NCCCN(C(=O)C(Cl)Cl)c1ccc([N+](=O)[O-])cc1
