D Correct answer
Explanation

Brute force attacks involve trying every possible key until the correct one is found. As CPU power increases exponentially (Moore's Law), the time required to brute-force encryption decreases proportionally. A 56-bit key that took years in the 1990s can now be broken in hours or days on modern hardware. This is why key lengths must increase over time to maintain security.
