Show answer & explanation
Correct answer: C
Memory access time units follow metric prefixes where each step down represents a factor of 1000 smaller. A Second is the largest unit listed. Following that, a Millisecond (1/1000 of a second) is larger than a Microsecond, which is larger than a Nanosecond, and finally a Picosecond is the smallest unit. Thus, the correct sequence from largest to smallest time duration is Second (E), Millisecond (A), Microsecond (D), Nanosecond (C), and Picosecond (B).
