Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.546\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CN1C(=O)COc2ccccc21)Nc1ccc(F)cc1
b C/C(CC(=O)Nc1cccc2c1CCCC2)=N\NC(=O)c1ccccc1N
c C=CCN1C(=O)/C(=C/C=C2/N(CC)c3ccc(S(=O)(=O)N(C)C)cc3N2CC)SC1=S
d O=C(NCc1ccc2c(c1)OCO2)C1CCCN(S(=O)(=O)c2cccc3cccnc23)C1
Answer: b. C/C(CC(=O)Nc1cccc2c1CCCC2)=N\NC(=O)c1ccccc1N
