C-4 is a type of plastic explosive known for its versatility and ability to be molded into different shapes, which allows for the alteration of the blast direction. This property is particularly useful in demolition and military applications, as it enables the user to focus the explosive force in specific directions for maximum effectiveness. The malleability of C-4 means it can easily adapt to various configurations to achieve the desired blast effects, such as shaping charges that can direct an explosion to penetrate armor or achieve other tactical objectives.

In contrast, TNT, RDX, and ANFO, while also being powerful explosives, do not possess the same level of moldability as C-4. TNT and RDX are generally used in more conventional forms and are less adaptable for precise shaping without additional components or containers. ANFO, being a mixture of ammonium nitrate and fuel oil, is typically used in bulk applications and is not molded into shapes like C-4, limiting its capability to alter blast direction effectively. This highlights the distinct advantages of C-4 in specific operational contexts, making it the correct answer to the question.
