Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.505\% 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] O=C(NCc1ccc(Cl)cc1Cl)c1ccc2nc[nH]c2c1
[b] CC(=O)c1ccc(N2CCN(C(=O)C(=O)c3cn(CC(=O)N4CCCCCC4)c4ccccc34)CC2)cc1
[c] O=C(Nc1cccc(O)c1)C1CCCN1C(=O)OCc1ccccc1
[d] CN1CCC(N(C)S(=O)(=O)c2ccc(NC(=O)c3cccc(C#N)c3)cc2)CC1
Answer: c. O=C(Nc1cccc(O)c1)C1CCCN1C(=O)OCc1ccccc1
