question 20:

Explanation:

To determine which feature most likely influenced the preference for Phone A, we compare the ratings of each feature between Phone A and Phone B. For Voice Quality, A (2.3) < B (2.8); for Camera, A (4.8) > B (4.5) with a difference of 0.3; for Navigation, A (3.1) < B (4.1); for Battery Life, A (4.5) > B (2.5) with a difference of 2.0. The largest positive difference (where A is rated much higher than B) is in Battery Life, making it the most impactful feature.

Answer:

D. Battery Life
