Task: Answer the MCQ question.
Question: Which compound exhibits a -7.597\% 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: O=C(NC1CCN(C(=O)Nc2ccccc2)CC1)C1CCCCC1
b: O=C(Nc1cccc(C(=O)Nc2cccc(Br)c2)c1)c1ccccc1
c: C=C1N(C)c2cc([N+](=O)[O-])c(N)cc2C1(C)C
d: O=C(O)Cn1cc(C(=S)N2CCOCC2)c2ccccc21
e: CCCc1cc(=O)[nH]c(Nc2ccc(O)cc2)n1
Answer: c. C=C1N(C)c2cc([N+](=O)[O-])c(N)cc2C1(C)C
