Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.207% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CCOC(=O)/C(N=Nc1cc(C(=O)O)cc(C(=O)O)c1)=C(\O)CCl
b.) CCn1c(C)cc2c(c1=O)C(c1ccc3c(c1)OCO3)C(C#N)=C(N)O2
Answer: a. CCOC(=O)/C(N=Nc1cc(C(=O)O)cc(C(=O)O)c1)=C(\O)CCl

CCOC(=O)/C(N=Nc1cc(C(=O)O)cc(C(=O)O)c1)=C(\O)CCl
CCOC(=O)/C(N=Nc1cc(C(=O)O)cc(C(=O)O)c1)=C(\O)CCl
