Explanation:

The correct option is (B) Internal. Internal hard drives are storage devices that are installed inside the computer's system unit (case). They are connected directly to the motherboard via data cables (like SATA) and power cables from the power supply. They are considered a permanent part of the computer's core configuration and are not designed for frequent removal or hot-swapping by the end-user, typically only being accessed for repair, replacement, or upgrades. Option (A) Static refers to non-moving components or a type of memory (SRAM), not a hard drive location. Option (C) External hard drives are designed for portability and easy connection/disconnection outside the system unit. Option (D) Remove is a verb, not a type of hard drive.
