Which Instagram surface allows a business to connect directly with individuals or groups of people?

The correct choice is the Direct messaging feature on Instagram. This surface facilitates personalized, one-on-one communication between businesses and users. Through Direct messages, businesses can engage in direct conversations, answer customer inquiries, provide support, and foster relationships that create a more personalized experience for the audience. This feature is particularly beneficial for building rapport and offering tailored responses, which can enhance customer loyalty and satisfaction.

Other surfaces, such as IGTV, the Feed, and Instagram Stories, are primarily designed for broadcasting content to a broader audience rather than facilitating direct communication. While these platforms are effective for sharing videos and promoting products, they do not provide the same level of interaction as Direct messaging. Therefore, when it comes to connecting with individuals or groups in a direct and personal manner, the Direct messaging function is the most suitable option.
