The problem provided involves simplifying a Boolean function using a Karnaugh map (K-map). The K-map you provided has variables $w$, $x$, $y$, and $z$, and is labeled as a 4-variable K-map.

Step-by-Step Simplification:

1. Identify groups of 1s in the K-map: In K-maps, we group 1s in powers of 2 (e.g., 1, 2, 4, or 8 cells), and these groups should be as large as possible.

2. Group identification:

   • The group of four 1s in the middle (spanning rows 00 and 01, and columns 10 and 11).
   • The two 1s at the bottom right form a group of two.
   • The two 1s on the leftmost side (spanning rows 10 and 11, and columns 00) form another group.

3. Derive simplified expressions from each group:

   • Group 1 (middle 4 cells): This group covers both $yz = 10$ and $yz = 11$, so $y = 1$ is constant, while $w$ and $x$ vary. The simplified term for this group is $y$.
   • Group 2 (bottom right 2 cells): This group covers $w = 1$, $x = 0$, $y = 1$, and $z$ can be 1 or 0. The simplified term for this group is $wx\overline{y}$.
   • Group 3 (leftmost 2 cells): This group covers $w = 1$, $x = 1$, and $z = 0$, with $y$ varying. The simplified term for this group is $w\overline{x}z$.

4. Final Simplified Boolean Function: The simplified Boolean expression is: $y + wx\overline{y} + w\overline{x}z$
