Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.120\% 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: CCCCCCCCCS(=O)(=O)N/N=C/c1cccc([N+](=O)[O-])c1
b: CC(C)(C)OC(=O)N(Cc1ccccc1)S(C)(=O)=O
c: COc1ccccc1-c1nnc(-c2ccc(N3CCOCC3)cc2)o1
d: O=C(NCC1COc2ccccc2O1)C1CCCN(S(=O)(=O)c2cccc3cccnc23)C1
Answer: d. O=C(NCC1COc2ccccc2O1)C1CCCN(S(=O)(=O)c2cccc3cccnc23)C1
