Options

B Focus clearly on horizontal and vertical lines in a picture at the same time.
Correct Answer
C See close objects clearly.
D Distinguish between different colors.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text specifies, "As a result, horizontal lines may be imaged in a different plane from vertical lines. Astigmatism may make it impossible, for example, to focus clearly on the horizontal and vertical lines in a picture at the same time."

Astigmatism affects how light rays entering at different orientations are focused.
