Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.181\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) Cc1[nH]n(-c2ccccc2)c(=O)c1C(c1ccc(O)c([N+](=O)[O-])c1)c1c(C)[nH]n(-c2ccccc2)c1=O
b) Cc1c(N(C)S(=O)(=O)c2cccc(C(=O)NC(C)C)c2)c(=O)n(-c2ccccc2)n1C
c) O=C(NCc1ccco1)c1ccccc1-c1ccccc1
d) COc1c(Cl)cc(C(=O)O)cc1Cl
Answer: c. O=C(NCc1ccco1)c1ccccc1-c1ccccc1
