The requirement for an EMT run with multiple bends is primarily focused on maintaining code compliance and ensuring the safety and stability of the electrical conduit. In this scenario, with three 90-degree bends and two 45-degree bends, the total number of bends exceeds the allowed limit for a continuous run without requiring additional support infrastructure.

Having an intermediate pull box is crucial because it allows for easier access to the wiring within the conduit and provides a means to change direction without exceeding the maximum number of bends permitted in a conduit run. The NEC (National Electrical Code) has guidelines that state when a run of conduit has too many bends, a pull box must be installed to facilitate pulling the wire through.

Different bend configurations or support brackets, while important in other contexts, do not address the need for accessibility in a scenario involving multiple bends. Therefore, the best answer is to have an intermediate pull box to ensure the conduit run is both functional and compliant with safety standards.
