To answer this question, we need to understand the concepts of synchronous and asynchronous methods.

Synchronous methods are those where the execution of code happens in a sequential manner. In other words, the code blocks are executed one after the other, and the program waits for each code block to finish before moving on to the next one.

On the other hand, asynchronous methods allow code execution to continue without waiting for a particular task to complete. Instead, a callback function or promise is used to handle the result of the asynchronous task when it completes.

In the case of the "Session" method, it is typically used to establish a connection between a client and a server. In most programming languages, the "Session" method is a synchronous method. This means that the program will wait for the session to be established before proceeding to the next line of code.

Therefore, the correct answer is:

B. Synchronous

To determine the output of the given code, let's go through it step by step:

1. We have a function named counter that takes an integer value as input. Inside the function, there is a static variable named count that is initialized to 0. The function adds the input value to the count variable and returns the updated value of count.

2. In the main function, we have two integer variables i and j declared.

3. There is a for loop that iterates from i = 0 to i <= 5. In each iteration, the counter function is called with the current value of i, and the returned value is assigned to j.

4. After the for loop, the value of j is printed using printf.

Let's track the value of j in each iteration of the for loop:

Iteration 1: i = 0

• j = counter(0). The initial value of count is 0, and value is 0. The updated value of count is 0.
• Therefore, j is assigned the value of 0.

Iteration 2: i = 1

• j = counter(1). The current value of count is 0, and value is 1. The updated value of count is 1.
• Therefore, j is assigned the value of 1.

Iteration 3: i = 2

• j = counter(2). The current value of count is 1, and value is 2. The updated value of count is 3.
• Therefore, j is assigned the value of 3.

Iteration 4: i = 3

• j = counter(3). The current value of count is 3, and value is 3. The updated value of count is 6.
• Therefore, j is assigned the value of 6.

Iteration 5: i = 4

• j = counter(4). The current value of count is 6, and value is 4. The updated value of count is 10.
• Therefore, j is assigned the value of 10.

Iteration 6: i = 5

• j = counter(5). The current value of count is 10, and value is 5. The updated value of count is 15.
• Therefore, j is assigned the value of 15.

After the for loop, the value of j is printed using printf. Therefore, the output of the code will be:

J = 15

So, the correct answer is D) 15.
