Task: Answer the multiple-choice question.
Question: Which compound has a 1.937\% 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 CNc1nc(OC)nc(N(C#N)CN2C(=O)c3ccccc3S2(=O)=O)n1
b COC(=O)c1ccc(COC(=O)CCC(=O)c2cccs2)cc1
c CN(c1ccccc1C(=O)NCC1CCCO1)S(C)(=O)=O
d O=C(CCc1ccccc1)C(=O)N1CCCC(C(=O)c2cccc(Cl)c2)C1
Answer: d. O=C(CCc1ccccc1)C(=O)N1CCCC(C(=O)c2cccc(Cl)c2)C1
