Acidic fruits are packed in

Answer: Option A

Acidic fruits are packed in R-enamel cans.
R enamel-lined cans preserve the colour of such highly coloured foods as berries, prunes, and beets, and prevent corrosion in pumpkin and squash.
It is their acidity level, combined with the proper heat processing of the filled jars that makes jars of these as safe as they are nutritious.
