• A. Riveter/ Pop Rivet Gun
• B. Thatching Rake

Answer: (C)

A motorized soil-prep tool is designed to loosen and aerate soil and mix in amendments. A power tiller fits that description precisely: it’s a motorized implement that breaks up compacted soil and blends in amendments like compost, manure, or lime. It’s available in many styles and capacities, from small soil mixers to larger units around 8 HP, which makes it versatile for different garden sizes. This directly matches the idea of alleviating soil compaction and evenly incorporating amendments. The other tools serve different trades—rivets for fastening metal, a thatching rake for lawn debris or thatch, and a block plane for woodworking—so they’re not appropriate for soil tillage or amendment mixing.
