Which of the following types of storage is used to transport information?

The correct choice for the type of storage used to transport information is a USB drive. USB drives are portable storage devices that can easily be connected to various computers and devices, allowing users to transfer and share files conveniently. They are designed specifically for this purpose, often being compact and lightweight, making them ideal for transporting data.

External hard drives can also be used for transporting information; however, they are typically bulkier and often intended for backup or additional storage rather than quick transport. Cloud storage, while useful for accessing data anywhere with an internet connection, does not involve physical transport of data like USB drives do. RAM, on the other hand, is used for temporary storage of data needed for active processes but is not designed for transport or portable use.
