Step 1: Determine the approximate period of invention or widespread use for each printmaking technique.
(B) Woodcut: The oldest form of printmaking, originating in China around the 9th century and appearing in Europe around 1400.
(C) Engraving: Developed from goldsmithing techniques in Germany in the 1430s. It became a major artistic medium shortly after the woodcut in Europe.
(D) Etching: Developed around the early 16th century as an alternative to engraving, using acid to incise the lines.
(A) Viscosity Printing: A modern multi-color intaglio technique developed in the 20th century by Stanley William Hayter.
Step 2: Arrange the techniques in chronological order from oldest to newest. The correct sequence is Woodcut, Engraving, Etching, Viscosity. This corresponds to (B), (C), (D), (A).
