Task: Answer the multiple choice question.
Query: Which drug has a 7.749% 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 additional words.
Options:
a) COC1=CCC2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])C2
b) COc1ccc(S(=O)(=O)N2CCCC(C(=O)NCCC3=CCCCC3)C2)cc1
c) CC(C)=NOCC(=O)Nn1c(C)nc2ccccc2c1=O
d) CN(C)c1ccc(C2(O)C(=O)c3ccccc3C2=O)cc1
Answer: a. COC1=CCC2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])C2
