Correct Answer: 37
Solution : The teacher wants to arrange the students in a square formation, where the number of rows equals the number of columns. The number of students, 1369, is a perfect square (since 372 = 1369). Therefore, the teacher can arrange the students in 37 rows with 37 students in each row. Hence, the correct answer is 37.
