Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.645\% 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. Cn1ncc(N=Cc2ccccc2[N+](=O)[O-])c1C(N)=O
b. COc1ccc(CCN=Cc2ccc(O)cc2)cc1OC
c. CNC(=O)c1csc(-c2ccc(Cl)cc2)n1
Answer: a. Cn1ncc(N=Cc2ccccc2[N+](=O)[O-])c1C(N)=O
