Question

Identify the set of all positive integers:

• A. $(10.1,0.2,3.2)$
• B. $(1,2,3,4)$
• C. $(12,-4,6,-8)$

Answer 1

The correct option is B

$(1,2,3,4)$

Explanation for the correct answer:

In set $1$the numbers are $(10.1,0.2,3.2)$

These numbers are in decimal from and hence cannot be considered as integers

In set $3$ the numbers are $(12,-4,6,-8)$

The numbers $-4,-8$ are negative integers.

Hence, this set does not contain all positive integers

In set $2$ the numbers are $(1,2,3,4)$

All the numbers in this set are positive integers.

In all the other sets there are either decimal or negative integer numbers

Hence (1,2,3,4) is the only set with positive integers.

Hence option $\left(B\right)$ is the correct answer.
