Task: Answer the multiple choice question.
Question: Which drug has a 1.784\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc([N+](=O)[O-])cc1N(CC(O)CN1CCCCC1)S(=O)(=O)c1ccc(C)cc1
b CC(=O)NC(CCS(C)(=O)=O)C(=O)Nc1ccc2c(c1)OCO2
c O=C(NCC1(N2CCCCC2)CCCCC1)c1cccc([N+](=O)[O-])c1
d O=C(COC(=O)C1(c2ccccc2)CCCC1)N1CCNC1=O
Answer: d. O=C(COC(=O)C1(c2ccccc2)CCCC1)N1CCNC1=O
