Using a reciprocating saw is the most suitable choice for making a hole in an exterior wall for placing a window. This tool is designed for demolition and cutting through various materials, including wood and drywall, which are common in exterior walls. The reciprocating saw's ability to cut in a straight line while being portable and easy to maneuver makes it ideal for such tasks, allowing carpenters to create openings accurately and efficiently.

The other tools, while useful in various situations, are not as effective for this specific application. For instance, a drill is typically intended for creating holes but lacks the necessary cutting capacity for larger openings required for windows. A circular saw is primarily used for making straight cuts on larger panels of material, which are usually too broad for the precise adjustments needed around a window frame. A hand saw, although it can be used for cutting, is less efficient and requires more physical effort and time to accomplish the task in comparison to a reciprocating saw.
