21 > 1.6

If you're only looking at the "immediate action" options it's 4.5% independence vs 1.6% unification

Grouping the camps together, the graph shows 25% vs 8% currently while not too long ago in 2018 it was 20% vs 16%. It's a contentious issue, and opinions wax and wane depending on the diplomatic situation with the only consistency being that the majority of people favor maintaining the status quo. However, I think as more of the older generations die off, much like in South Korea, identification with a cross-border national project will likely diminish.
