Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.952\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] Cc1cc(NC(=O)CSc2nnc(-c3cccs3)n2N)no1
[b] CC(C)CCn1c(N)c(C(=O)NCc2cccs2)c2nc3ccccc3nc21
[c] O=C(O)c1ccccc1Nc1ccc([N+](=O)[O-])c2nonc12
[d] CCN(CC)c1ccc(C=C2C(=O)N(C)C(=S)N(C)C2=O)o1
Answer: c. O=C(O)c1ccccc1Nc1ccc([N+](=O)[O-])c2nonc12
