Choose which one is the different number from the following
Correct answer: B. 131
- A. 125
- B. 131
- C. 130
- D. 138
Explanation
The correct answer is Option B: 131. This number is unique because it is a prime number, meaning it can only be divided by 1 and itself without resulting in a fraction. On the other hand, the other options-125, 130, and 138-are all composite numbers. 125 can be factored into 5 x 5 x 5, 130 into 2 x 5 x 13, and 138 into 2 x 3 x 23, all of which have factors other than 1 and themselves. Therefore, 131 stands out as the only prime number among the choices.

About Critical Thinking
Critical thinking examines how conclusions follow from evidence, including claims, assumptions, arguments, inferences and relevant facts.
