Step-by-step Solution:

\[ \textbf{Question:} \quad \text{Which secondary storage device has the fastest access time?} \] \[ \text{Options: Optical Drive, Magnetic Tape Drive, Hard Disk Drive (HDD), Solid State Drive (SSD)} \] --- \[ \textbf{Access Time Comparison:} \] \[ \begin{array}{ll} \text{Magnetic Tape Drive} & \text{Very slow (sequential access only)} \\[6pt] \text{Optical Drive (CD/DVD/BD)} & \text{Slower than HDD, random access but limited by rotation/seek time} \\[6pt] \text{Hard Disk Drive (HDD)} & \text{Faster than optical, mechanical movement limits speed} \\[6pt] \text{Solid State Drive (SSD)} & \text{Fastest, no moving parts, purely electronic access} \end{array} \] --- \[ \boxed{\text{Solid State Drive (SSD) has the fastest access time.}} \]
