Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.031\% 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) COC(=O)C1=C(N)Oc2cc(C)n(Cc3cccnc3)c(=O)c2C1c1cc(OC)ccc1OC
b) Cn1c(CN2CCCC2)nc2cc(NC(=O)c3ccco3)ccc21
Answer: a. COC(=O)C1=C(N)Oc2cc(C)n(Cc3cccnc3)c(=O)c2C1c1cc(OC)ccc1OC
