Task: Please answer the multiple choice question.
Question: Which molecule has the highest acute oral toxicity rat LD50?
Constraint: Even if you are not sure, you must pick either a, b, c, d, or e without using any additional words.
Options:
a: C=CCN(CC=C)C(=O)C(Cl)Cl
b: CC(C)=CCC1=C(O)C(C(=O)CC(C)C)=C(O)C(CC=C(C)C)(CC=C(C)C)C1=O
c: CC(C)(Oc1ccc(CCNC(=O)c2ccc(Cl)cc2)cc1)C(=O)O
d: C=C(C)C(=O)OCCSCC
e: Cc1cc(C(C#N)c2ccc(Cl)cc2)c(Cl)cc1NC(=O)c1cc(I)cc(I)c1O
Answer: e
