B. Round transition
C. Rectangular shift
D. Square to round transition

The correct answer is: D. Square to round transition

A round to rectangular fitting in HVAC installation is commonly referred to as a "Square to round transition." This fitting is specifically designed to connect a round duct to a rectangular duct in the HVAC system. It facilitates the smooth flow of air while transitioning between different duct shapes. The other options, such as "Circular converter," "Round transition," and "Rectangular shift," do not accurately describe this specific type of fitting used in HVAC installations.
