A virtual private network (VPN) provides a secure connection for information transmitted over the public Internet.
Step-by-step explanation:
A virtual private network (VPN) is a technology that provides a secure connection for information transmitted over the public Internet. Option A is the correct answer.

This is particularly important when sharing personal, financial, or medical information with businesses and organizations, as it ensures that the data remains private and protected from unauthorized access.
