To answer this question, you need to understand bitmap checkpoints and what they are used for.
Bitmap checkpoints are used to compare an actual image or screenshot with an expected image or screenshot. They are sensitive to the following factors:
A) Image size and object type - This option is incorrect because bitmap checkpoints do not specifically consider the object type. They compare the pixels of the entire image, regardless of the objects within it.
B) Object type and image type - This option is incorrect because bitmap checkpoints do not specifically consider the object type or image type. They compare the pixels of the entire image.
C) Screen resolution and object type - This option is incorrect because bitmap checkpoints do not specifically consider the screen resolution or object type. They compare the pixels of the entire image, regardless of the screen resolution or objects within it.
D) Screen resolution and image size - This option is correct. Bitmap checkpoints are sensitive to both the screen resolution and image size. The comparison between the actual and expected images takes into account the pixel values, which can vary depending on the screen resolution and image size.
Therefore, the correct answer is D) Screen resolution and image size.
