Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.780\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CNc1ccccc1C(C)(C)c1cc(-c2ccco2)n[nH]1
b: CCN(CC(O)Cn1c2ccccc2c2ccccc21)S(=O)(=O)c1ccc(C)cc1
c: CC1CCCC(C)N1C(=O)Cn1cnc2cc([N+](=O)[O-])ccc2c1=O
d: Cc1ccc(C2N=C(N)Nc3nc4ccccc4n32)cc1
e: COc1cc(C)c(Cl)cc1S(=O)(=O)NCc1ccccn1
Answer: c. CC1CCCC(C)N1C(=O)Cn1cnc2cc([N+](=O)[O-])ccc2c1=O
