Which feature permanently alters the state of a transistor on a computer chip if the bootloader is modified or altered?

• A. Rooting
• B. Containerization (Mobile)
• C. End of Life (EOL)
• D. eFuse

Answer: (D)

A hardware mechanism known as an eFuse stores one-time programmable bits in silicon. Once an eFuse bit is set, it permanently changes a transistor state and remains non-volatile. In the boot process, burning an eFuse bit can lock the device to a trusted boot image or mark the chip as tampered, so even if someone re-flashes the bootloader, the device won’t run an insecure or unsigned image. This irreversible state is exactly why eFuse is the correct choice here. The other terms relate to software or product status, not to permanent hardware changes. Rooting is a software privilege gain, containerization is OS-level isolation, and End of Life is a product lifecycle designation.
