Final answer:

To search an array until finding a specific item, you should use a while loop. It will repeat a block of code as long as a certain condition is true. The correct answer is B.

Step-by-step explanation:

In order to search an array until you find a specific item, you should use a while loop. A while loop will continue repeating a block of code as long as a certain condition is true. In this case, you can use the while loop to iterate through each element of the array and check if it matches the item you are looking for.

Here's an example:

int[] numbers = {1, 2, 3, 4, 5};
int target = 3;
int index = 0;
while (index < numbers.length && numbers[index] != target) {
index++;
}
if (index < numbers.length) {
System.out.println("Item found at index " + index);
} else {
System.out.println("Item not found.");
}

In this example, the while loop iterates over the array until it finds the item "target" or reaches the end of the array. If the item is found, it prints the index where it was found. Otherwise, it prints "Item not found."

To search an array for a specific item, a while loop should be used to iterate until the item is found, with an if statement nested inside to check for a match.

If you want to use a loop to search an array until you find the item that you are looking for, the best option would be b. a while loop. A while loop will continue to iterate over the array until a certain condition is met, such as finding the target item. An if statement is usually nested within the while loop to check if the current item matches what you're looking for. This is also commonly referred to as a search algorithm. If the condition never becomes true, it is essential to include a condition to break out of the while loop to avoid an infinite loop.
