Where should I put the delete button?

I have a sidebar which shows all links that users saved. Since it's just a sidebar, I want to keep it as simple/clean as possible. Thus I use the cross icon next to the link for deletion.

Option 1

pros: easy to know which link to delete

cons: delete buttons not align

Option 2

pros: easy to know which link to delete, delete buttons align

cons: it seems weird to put the delete button at the beginning

Option 3

pros: delete buttons align, also align with the collapse icon, which looks good.

cons: delete buttons are far away from the link and may cause the wrong deletion. (Add a border around the row or separate each row using different color can mitigate this problem but the sidebar looks messy)

Overall I prefer option 3 but how to ensure users click the right delete icon?
