Submit

option A is the correct answer.

Step-by-step explanation:

In the fruit juice recipe, the ratio by volume of orange juice to pineapple juice to apple juice is 2:7:5. The total ratio would be the sum of the proportions of orange juice, pineapple juice and apple juice. It becomes

2 + 7 + 5 = 14

Therefore, the number of liters of pineapple juice needed to prepare 3 liters of fruit juice would be

7/14 × 3 = 3/2 liters
