CREATE TABLE students (
student_id INT PRIMARY KEY,
student_name VARCHAR(50),
marks INT
);
student_id INT PRIMARY KEY,
student_name VARCHAR(50),
marks INT
);
INSERT INTO students (student_id, student_name, marks)
VALUES (1, 'Alice', 80),
(2, 'Bob', 85),
(3, 'Charlie', 90);
VALUES (1, 'Alice', 80),
(2, 'Bob', 85),
(3, 'Charlie', 90);

Consider the following SQL code:CREATE TABLE students ( student_id INT...
Understanding the SQL Code
The SQL code provided is designed to create a table and insert data into it, followed by a query that retrieves specific information.
1. Table Creation
- The table `students` is created with three columns:
- `student_id`: An integer that serves as the primary key.
- `student_name`: A string (up to 50 characters) for the names of the students.
- `marks`: An integer representing the marks obtained by each student.
2. Data Insertion
- Three records are inserted into the `students` table:
- (1, Alice, 80)
- (2, Bob, 85)
- (3, Charlie, 90)
3. Query Execution
- The `SELECT` statement retrieves the `student_name` column from the `students` table.
- It orders the results by the `marks` column in descending order, ensuring that the highest marks appear first.
- The `LIMIT 2` clause restricts the output to the top two results.
4. Result Interpretation
- The marks for the students are:
- Alice: 80
- Bob: 85
- Charlie: 90
- When ordered by marks in descending order, the list appears as:
1. Charlie (90)
2. Bob (85)
- The `LIMIT 2` returns the names of the top two students: Charlie and Bob.
Conclusion
Based on the ordered results, the output of the SELECT statement is:
- Charlie, Bob
Thus, the correct answer is not option 'C' as mentioned, but rather it should be option 'B' (Bob, Charlie).
