What is an expected element of professional attire in the workplace?

Choosing formal business attire as an expected element of professional attire in the workplace is correct due to its representation of professionalism, respect, and a serious approach to work. Formal attire typically includes items such as suits, dress shirts, blouses, and dress shoes, which not only comply with most professional dress codes but also foster a sense of authority and competence among colleagues and clients.

In many corporate environments, formal business attire serves to create a cohesive image and demonstrates that one is prepared to engage in a professional setting. It also helps in setting the tone for the workplace culture, promoting an atmosphere conducive to productivity and professionalism.

The other options, while they may have their appropriate contexts, do not convey the same level of professionalism required in typical workplace settings. Casual clothing, comfort-focused outfits, and sporty attire are generally perceived as too relaxed or informal for environments that prioritize a polished and professional appearance.
