Solution
The correct option is A Cardboard sheet
To identify the material that will block the sunlight, we need to understand that the material should not be able to allow passage of any light through it.
Transparent object: Allows light to completely pass through it.
Translucent object: Allows light to partially pass through it.
Opaque object: Does not allow the light to pass through it.
Butter paper: Translucent material
Tinted glass: Translucent material
Plastic wrap: Transparent material
Cardboard sheet: Opaque material
Thus, the correct choice is a cardboard sheet.
