Solution:

Given:
Number of students = 1369

To find:
Number of students in the last row

Calculation:
To arrange the students in an equal number of rows and columns, we need to find a number which is a perfect square less than or equal to 1369.
1369 is a perfect square of 37 (37 * 37 = 1369).
Hence, the number of students in the last row will be 37.
Therefore, the correct answer is option A.
