Which of the following is the standard keyboard layout ?

A keyboard layout describes the arrangement of letters, numbers, and symbols on the keys. The layout adopted as the worldwide standard for English-language keyboards is named after the first six letters that appear on its top-left row of letter keys: Q, W, E, R, T, Y. This layout was designed in the 1870s for early typewriters and has remained the default arrangement on almost every computer, laptop, and phone keyboard sold today.

The alternative layouts named among the choices exist but are not the standard. One is a later redesign intended to reduce finger movement by grouping the most frequently used letters on the home row; it is used by only a small number of typists who deliberately switch to it. Another is the standard layout used mainly in French-speaking countries, named after the first letters on its own top row, and it rearranges several keys compared with the English standard. A layout that simply lists the alphabet in order (A, B, C, D) is not used in any real keyboard because it would be inefficient for touch-typing, since common letter combinations would not be positioned for quick, alternating finger movement.

Remember that "standard" in this context means the default layout shipped on most computers and recognised internationally, and that is the one named after its own first six top-row letters.
