The term "CMYK" stands for "Cyan, Magenta, Yellow, and Key(Black)," and it`s primarily associated with the offset printing process used in color printing.

Option 1, `Railway signaling,` is incorrect as CMYK does not have any particular relevance to railway signaling which is involved with directives used to operate trains securely.

Option 2, `Navigation,` is also not the correct answer. Navigation involves directing a path or course of action and does not require the use of the CMYK color model.

Option 3, `Offset printing,` is the correct answer. CMYK is a color model used in this process to produce a full range of colors. Each print is made by using four plates: one for each color (Cyan, Magenta, Yellow, and Black).

Option 4, `Electronic voting statements` is not correct. CMYK is a printing process and doesn`t relate to electronic voting statements, which are associated with political or data processing areas.
