The correct option is A 25
From the key, we know that each picture in the pictograph represents 5 votes.
Thus,
Number of votes for blue: 5 × 5 = 25
Number of votes for green: 3 × 5 = 15
Number of votes for white: 4 × 5 = 20
Number of votes for yellow: 1 × 5 = 5
Number of votes for pink: 2 × 5 = 10
Hence, the most voted color was blue and it got 25 votes.
