The correct answer is SELECT student_name, grade FROM math_class, because the SELECT statement is used to specify which columns you want to retrieve from a table, and FROM specifies from which table to pull the data. The table named 'math_class' likely includes the student names and grades specific to the math class. The incorrect answers either attempt to perform an operation not related to data retrieval (CREATE or UPDATE) or do not specify the necessary columns and table (SELECT * FROM students would retrieve all columns, which probably includes more information than the teacher is asking for).
