while (index < prices.length) { if (prices[index] > 20) { total += prices[index]; } index++; }Answer and explanation
Correct answer
A. Add an if condition inside the loop
Why
By adding an 'if' condition inside the loop to check if 'prices[index]' is greater than 20, only those items will be added to 'total'. This filters the items based on price.
