Answer:
By using the artist's Pointillism, he wanted to give less spontaneity to the work and reinforce the effect of colors.
Explanation:
Pointillism highlighted the colors, making the work more vivid and eye-catching, even with the tiny blank spaces. This technique took away the air of spontaneity that the brushstrokes promoted. This created more focused works and with a mood of control, focus and concentration, giving the work a rigidity that other techniques did not promote. Pointillism was very influential, being a highly used technique to this day, in addition to influencing the emergence of other techniques.
A and C are both correct to a degree. He is well known for his peculiar geometric forms in his paintings, which were not at all realism, but rather a style called cubism. During his Blue Period, his paintings were literally painted in blues, and were true to the answer in C. One particular painting depicts an elderly man playing a guitar with a frown on his face looking incredibly sad and upset. I would probably select C because it describes his Blue Period in contrast to his typical style, which is described in A.
