Final answer:
Lee Krasner influenced her fellow Abstract Expressionist, Jackson Pollock, with her 'all-over' painting technique, and both artists were significant figures in the Abstract Expressionism movement.
Step-by-step explanation:
Lee Krasner's early work was influenced by Piet Mondrian's grid paintings before her "all-over" technique influenced her fellow Abstract Expressionist Jackson Pollock. The correct answer to fill in the blank is (c) Abstract Expressionist. Krasner was a key figure in the post-World War II art scene and played a critical role in the development of Abstract Expressionism.
Her husband, Jackson Pollock, became renowned for his unique style of drip painting, which was a radical departure from traditional methods of painting and helped define the movement. Both Krasner and Pollock explored new ways of creating art, seeking to express complex emotions and ideas without relying on representational forms.
Abstract Expressionism itself is characterized by spontaneous, automatic, or subconscious creation, and a significant focus on the act of painting itself as much as the final artwork.
