boolean inStock = true;
double userBalance = 150.0, itemPrice = 100.0;
if (inStock) { if (userBalance >= itemPrice) { checkout(); } }Answer and explanation
Correct answer
D. If (inStock) { if (userBalance >= itemPrice) { checkout(); } }
Why
Checking if the item is in stock first is logical because it avoids unnecessary balance check if the item is unavailable. Nested ifs provide clear separation of conditions.
