You write a word with each letter under the previous letter. This would be a good way to help you remember the definition of
A. altitude (a measure of height above the ground)
O
B. row (a number of things in a straight line)
a
C. maximum (the most possible)
D. column (an upright support)

D). Column (an upright support)

Explanation:

As per the question, the technique of jotting down a word with a letter and the next word with the next letter right under the previous one would best help the student to learn the definition of 'column.' The 'Column' is defined as 'a vertical line of entries from top to bottom or a solid upright structure.' Thus, when the student would write the words under words, he would understand that 'column' stands for a 'vertical form or structure of things moving from top to bottom.' Therefore, option D is the correct answer.
