Which one of the following happens during ripening?

Question

BlackTom AI · Accepted Answer

When evaluating what happens during fruit ripening, it's helpful to recall the chemical changes that occur: acid content typically decreases while sugars accumulate, making the fruit sweeter and less tart.
Option a: 'Acid levels rise and sugar levels rise' would imply both acidity and sweetness increase, which is not typical of ripening; acids usually decrease, so this is inaccurate.
Option b: 'Acid levels fall and sugar levels fall' suggests sugars also decrease, which contradicts the common ripening process where starches are broken down into sugars and overall sweetness increases.
Option c: 'Acid levels fall and sugar levels rise' matches the standard ripening pattern—decreasing acidity and increasing sugar content due to the breakdown of acids and starch-to-sugar conversion.
Option d: 'Acid levels rise and sugar levels fall' reverses the expected trend, indicating more acidity and less sugar, which is characteristic of unripe or certain damaged fruits, not typical ripening.
In summary, the ripening process is characterized by decreasing acidity and increasing sugar content, which aligns with option c. This reflects the chemical transformations that reduce tartness and enhance sweetness during maturation.
