Solution (By Examveda Team)

Explanation:
Let's break down what types of variables are and which one fits exam GPAs.

চলক (Variable): A variable is something that can change its value.

বিচ্ছিন্ন চলক (Discrete Variable):
These can only take specific, separate values. Think of counting things. You can have 1 student, 2 students, or 3 students, but not 2.5 students.

অবিচ্ছিন্ন চলক (Continuous Variable):
These can take any value within a given range. Think of height. Someone can be 5.2 feet tall, 5.25 feet tall, or 5.257 feet tall. It can have decimal values.

পরীক্ষার প্রাপ্ত জিপিএ (Exam GPA):
GPAs are usually expressed with decimal points (like 3.5, 4.0, 2.75, etc.). It can take any value within a range.

Therefore, since exam GPAs can take on decimal values and are not limited to whole numbers, they are considered অবিচ্ছিন্ন চলক (Continuous Variables).

The correct answer is Option B: অবিচ্ছিন্ন চলক.
