Show answer and explanation
Correct Answer

B. 4/5 / 4/5

Explanation

Step 1: For the ellipse a² = 25 and b² = 9. Step 2: e = √(1 - b²/a²) = √(1 - 9/25)=4/5. Step 3: Eccentricity of an ellipse is always less than 1.

Step 1: ellipse में a² = 25 और b² = 9 है। Step 2: e = √(1 - b²/a²) = √(1 - 9/25)=4/5। Step 3: ellipse में eccentricity हमेशा 1 से कम होती है।
