assuming it is stored safely how long after It was prepared can refrigerated food be sold or served 1-7 days b-10 days c-14 days d-20 days

1-7 days

Explanation:

But, ideally 4 days should be the maximum for prepared food to be refrigerated before it is sold or served.

Leaving food refrigerated for a long time makes it to lose its nutrients.  Some foods like potatoes, meat, eggs, chicken, etc. can become harmful or poisonous, especially when you reheat them before eating.  That is why it is right to adhere to proper routines for refrigerating food and also preparing and serving the food.  Some healthy food are better eaten immediately after their preparation.
