To correctly make "el helado sabroso" plural, you should note that "helado" is a masculine noun and "sabroso" is a masculine adjective. The correct plural form is "los helados sabrosos."
Here’s a breakdown of the incorrect forms you provided:
- "El helados sabroses" - "El" should be "los" for plural, and "sabroses" is not the correct form.
- "El heladoses sabroso" - "El" is singular, so it should not be paired with "heladoses," which is incorrect.
- "Los helados sabrosos" - Correct!
- "Las helado sabroses" - "Helado" should be "helados" (plural) and since "helado" is masculine, "las" should not be used; it should be "los."
Therefore, the only correct answer is "Los helados sabrosos."
