Final answer:
To cut thermoplastics, you can use a Hot Knife. A hot knife is a tool specifically designed for cutting thermoplastics. It uses heat to soften the plastic, making it easier to cut through. The option (D) is correct.
Step-by-step explanation:
To cut thermoplastics, you can use a Hot Knife. A hot knife is a tool specifically designed for cutting thermoplastics. It uses heat to soften the plastic, making it easier to cut through. When the hot knife is pressed against the plastic, it melts a narrow groove, creating a clean and precise cut.
In contrast, options A, B, and C are not suitable for cutting thermoplastics. A hacksaw, a band saw, and a circular saw are typically used for cutting different materials like metals, wood, or plastics that don't require melting. Therefore, option (D) is correct.
