A hard disk drive contains platters (magnetic disks) that spin and store data. Motherboards and riser boards are circuit boards in the computer, not part of the HDD. Lasers are used in optical drives, not magnetic hard drives.

Optical, Mechanical, and Optical-Mechanical are all real mouse technologies. Mechanical mice use a ball, optical mice use LED light, and optical-mechanical combines both. 'Motorized' is not a recognized mouse technology - it appears to be a fabricated option.

Vinton Cerf, often called the 'Father of the Internet,' co-developed TCP/IP protocols with Bob Kahn. This foundational work enabled the modern internet's development.

The speed of light in vacuum is approximately 3×10^8 m/s, which equals 3×10^10 cm/s. Option B correctly converts this value to centimeters per second, while the other options use incorrect units or magnitudes.

1 atomic mass unit (amu) equals 931.5 MeV/c² in energy units, which is approximately 931 × 10^5 eV/c². This conversion is fundamental in nuclear physics for calculating mass-energy equivalence.
