Answer

### Therefore, based on the properties and uses of the different tools, the correct answer is A) Lead knife. This option is most suited for marking lead as it offers the necessary durability, clear visibility, and high precision. ^

Explanation

## The question asks about a tool that should be used to mark out leads. Comparing and examining all the available options:- **Lead Knife (Option A):** A lead knife has a specially angled sturdy blade, which makes it ideal for cutting out lead and making markings. - **UV pen (Option B):** Ultraviolet (UV) pens use an ink visible under UV light, but the ink is not properly visible on lead thus making it not ideal for marking lead.- **Chalk (Option B):** Chalk, while often used in construction and fabrication settings, does not offer the precision or permanence necessary for marking lead.- **Spirit based marker pen (Option D):** Spirit-based marker pens are used on a variety of surfaces, including metals, but they may experience issues with being visually distinct or durable on lead due to its different material properties.
