What effect occurs when dark blue text on a black background is given a white outline?

Answer and explanation

Correct answer: सफेद बाह्यरेखा सीमा-विरोधाभास बढ़ाकर पठनीयता सुधार सकती है। The white outline may improve readability by increasing boundary contrast.

The governing concept is boundary contrast. Dark blue and black have relatively similar darkness, so the letters may lack a clear separation from the background. A white outline introduces a light edge around each letter, increasing local value contrast and making the text easier to identify and read. Therefore option B is correct. The outline does not change the text size, remove hue contrast, or make blending worse.
