Solution

The correct option is D Variable mapping

Variable mapping is not a type of function.

A karnaugh map (K-map) is a pictorial method used to minimize Boolean expressions without having to use Boolean algebra theorems and equation manipulations. A K-map can be thought of as a special version of a truth table. Using a K-map, expressions with two to four variables are easily minimized.

When referring to programming, or layout of a software program or hardware device, a map refers to the documentation that describes its overall structure. When referring to networks, a map or mapped drive refers to a link to another computer, share, or printer.

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions.
