Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.048\% 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 CSC1=NSC2=NC(=O)/C(=C/c3coc4ccc(O)cc4c3=O)C(=N)N12
b CCOC(=O)C1CCN(C(=O)c2ccc(OCC)c(OCC)c2)CC1
Answer: a. CSC1=NSC2=NC(=O)/C(=C/c3coc4ccc(O)cc4c3=O)C(=N)N12
