- A.
Smaller
- B.
Larger
Correct Answer
B. LargerExplanation
The larger the number of pixels, the finer the details the camera can potentially record. This is because a larger number of pixels means that there are more individual dots of color that make up the image. With more pixels, the camera can capture more information and provide a higher level of detail in the resulting image.Rate this question:
