Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.764\% 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 CCn1c(C)c(C)c2cc(C(=O)NCCCN3CCN(C)CC3)ccc21
b COc1ccccc1C/C(N)=N/OC(=O)COc1cc(C)cc(C)c1C
c Cc1nn(-c2ccccc2)c2c1C(c1cccc([N+](=O)[O-])c1)N(c1ccccc1)C(=O)N2
Answer: c. Cc1nn(-c2ccccc2)c2c1C(c1cccc([N+](=O)[O-])c1)N(c1ccccc1)C(=O)N2
