Final answer:
The correct answer to projecting a professional and friendly image is C) Smiling and being polite. Ignoring customer requests, casual attire, and indifference to customer concerns are not considered professional.
Step-by-step explanation:
Projecting a professional and friendly image in a work environment includes smiling and being polite, which encompasses a range of behaviors such as providing excellent customer service, maintaining a professional appearance, and treating everyone with respect. While organizations may have varied cultures with different dress codes or informal communication styles, it's important to be observant and adapt while still being respectful and professional. Ignoring customer requests, dressing inappropriately for the workplace, and showing indifference to customer concerns are not considered professional or friendly behaviors. On the other hand, a positive attitude, punctuality, and effective time management contribute to one's professional image and are key to job performance and satisfaction.
