Final answer:
Social media is the best communications tool to share how-to videos and photos with a tech-savvy workforce. Therefore, the correct option is A.
Step-by-step explanation:
Using social media would be the best way to communicate with a tech-savvy workforce by posting how-to videos and photographs. Multimedia content can be shared visually stimulating and conveniently through platforms like an internal company social network.
Because of these platforms' interactive content features and easy-to-use interfaces, tech-savvy people frequently favour them. Although in-person meetings (b), phone conversations (c), and company newsletters (d) have their uses, they may not be as effective in reaching a tech-savvy audience that values the ease and interaction provided by social media platforms with dynamic and visual material.
Therefore, the correct option is A.
