Answer

B. varnished wood. Explanation 1. Identify surface characteristics "Moderately slippery" surfaces are those that have some friction but can still cause slipping. 2. Analyze each option A. Unfinished wood typically has a rough texture, providing more friction. B. Varnished wood is smoother than unfinished wood, reducing friction moderately. C. Polished marble is very smooth, offering low friction and high slipperiness. D. Ice is extremely slippery due to its smooth surface and low friction. 3. Determine the moderately slippery surface Among the options, varnished wood fits the description of being moderately slippery due to its smoother finish compared to unfinished wood but not as slippery as polished marble or ice.
