Task: Answer the multiple choice question.
Question: Which drug has a 4.451% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCOC(=O)C1CCCN(C(=O)c2cn(CC(C)C)c(=O)c3cc(OC)c(OC)cc23)C1
b) COC(=O)c1ccccc1NC(=O)c1cc(-c2ccc(C)cc2)on1
c) CC(C)n1c(N2CCN(CC(=O)Nc3ccc4c(c3)OCCO4)CC2)nc2ccccc21
d) O=C(CSc1nc2ccc([N+](=O)[O-])cc2[nH]1)c1ccc2ccccc2c1
Answer: d. O=C(CSc1nc2ccc([N+](=O)[O-])cc2[nH]1)c1ccc2ccccc2c1
