Zenbook warranty

[77dmj]

I've just registered a Zenbook S16 in the UK and I'm now confused by the warranty extension process. I'm faced with these options:

It suggests the best deal is the one highlighted at the top "2 year standard" at £62.99 with the 10% discount offer applied. However below I can get "2 year extension with 3 year accidental" for £44.99. What advantage does the £62.99 have? Also if I were to go for the £62.99 deal, for not a lot more I could get premium onsite for £80.99. Does the premium include everything, e.g. accidental damage.

I can't find a breakdown of the specific covers anywhere.

Any help deciphering this would be appreciated.
