Concept:This question tests the correct arrangement of words in an English phrase that describes a person's quality.
Explanation:The phrase must sound natural and follow standard English word order.
When we describe someone's ability or future promise, we say they are "a person of great quality."
Here, the quality is "potential," so the correct form is "a student of great potential."
This means Ade is a student who has great potential.
Option A changes the word order and sounds unnatural.
Option C changes the meaning by suggesting the student itself is great potential.
Option D has completely incorrect word order.
Therefore, only option B gives the proper idiomatic expression.
Answer:B. a student of great potential
