Step-by-step explanation:
To clean up grease on the floor of a restaurant, the best product option would be d) Signet Degreaser. Degreasers are formulated specifically to break down grease and oil, which makes them more effective for kitchen environments where such spills are common. While the other Signet products like Green Floor Cleaner, Heavy-Duty Floor Cleaner, and All-Purpose Cleaner are valuable for general cleaning tasks, a Signet Degreaser is designed to tackle heavy kitchen grease which can be quite stubborn and slippery, making it hazardous in a busy restaurant setting. Signet Heavy-Duty Floor Cleaner is designed for deep cleaning, but it may not be as effective against grease as the degreaser. Signet All-Purpose Cleaner is a versatile cleaner but may not have the specific formulation to effectively tackle grease on floors.
