Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 14.174\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)c1cccnc1C(=O)O
[b] CC(/C=C/c1ccc2c(c1)OCO2)=N/NC(=O)COc1ccc(C)cc1
Answer: a. O=C(O)c1cccnc1C(=O)O
