while (index < prices.length) { total += prices[index]; index++; }Answer and explanation
Correct answer
A. The total of all prices
Why
The loop iterates over each element in the 'prices' array, adding each element's value to 'total'. When 'index' equals 'prices.length', the loop exits, resulting in 'total' being the sum of all prices.
