My question comes from Strings and Keywords topic in chapter CSS Properties, Elements, Functions & Tables of CSS

Answer 1

The correct answer is (c) 6-Hex Color

To explain: CSS’s six-digit hexadecimal format is the same as color defined in (X)HTML. The format specifies color as #rrggbb, where rr is the amount of red, gg the amount of green, and bb the amount of blue, all specified in a hexadecimal value ranging from 00 to FF.
