You need to create the layout shown, which defines five content areas:Logo and page titleMenuMain...

The correct answer is D because the layout shown is a named-area CSS Grid layout. The mockup contains five semantic regions: the top header area for the logo and page title, a left-side menu, a central main content area, a right-side additional content area, and a bottom copyright/contact area. In CSS Grid, this type of visual structure is defined with grid-template-areas, where each quoted string represents one grid row and each repeated name represents how far that area spans across columns. In option D, heading spans the full top row, menu occupies the left column across the lower rows, content fills the main center region, right fills the additional content region, and contact spans the bottom row to the right of the menu. Option A only defines row and column sizes and does not name the five content areas. Options B and C are invalid for this purpose because named layout strings do not belong in grid-template-rows or grid-template-columns.
