Explanation:
<em><u>Ambassadeurs </u></em><u>poster by Henri de Toulouse-Lautrec is the one done in the lithography technique. </u>
Lithography is based on the immiscibility of oil and water. It is very suitable for free drawing and painting, as well as producing the work in many copies.<u> The print is applied to the smooth surface, allowing the artist to have complete freedom of movement and manner, and it is later reproduced on the paper or other material. </u>This makes it suitable for posters, like the example we see here. 
 
The first artwork is part of Andy Warhol's <em>Endangered Species</em>, and while it can look at what we expect of lithography it is done in the s<u>creenprint technique.</u>
The second artwork is Dürer's <em>Rhinoceros</em>, done in a <u>woodcut</u>. While it does look like lithography because of its spectacular details and exquisite mastery, it is too early for this technique.<u> Dürer did this piece in 1515, while lithography was invented only in 1796.</u>

Pretty sure she dropped and poured paint onto a canvas, because she used oil paints and when she diluted them it strongly resembled watercolours.
