Task: Answer the MCQ question.
Question: Which compound exhibits a -0.476\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cc1nn(-c2ccccc2)c2c1C(c1c(C)[nH]c(C#N)c1C)C(C#N)=C(N)O2
[b] Cc1cc(C(=O)CN2C(=O)C3CC=CCC3C2=O)c(C)n1-c1ccccc1
[c] O=C(NCc1ccco1)C1CCCN(S(=O)(=O)c2cnc[nH]2)C1
Answer: c. O=C(NCc1ccco1)C1CCCN(S(=O)(=O)c2cnc[nH]2)C1
