Final answer:
Highly detailed rendering is not a characteristic of Impressionism or Morisot's 'The Beach at Nice'; the movement is known for its loose brushstrokes, emphasis on light, and outdoor scenes.
Step-by-step explanation:
The characteristic that is NOT a feature of Berthe Morisot's 'The Beach at Nice' or Impressionism in general is d) Highly detailed rendering. This artistic movement, including Morisot's work, is known for its loose brushstrokes, use of light to capture quickly shifting atmospheric conditions, and scenes often painted en plein air to capture the modern, fast pace of life. The lack of high detail is intentional to focus on overall visual effects and the sensation of seeing light change incessantly in the landscape. Instead of a highly detailed rendering, Impressionist paintings are characterized by a luminous tonality and a decorative pattern of paint that unifies figures, background, and water into a continuous sweep of texture and color.
