Your toast and marmalade is on the table.

[Freeguy]

Which one is right?

1. Your toast and marmalade is on the table.
2. Your toast and marmalade are on the table.

That all depends on if you consider "toast and marmalade" to be one thing or separate things.

If the marmalade is already on the toast and is being served as one item, then you could say "is."

If they are separate items, then use "are."
