### Solution:

Concept: The entire numbers {1, 2, 3, …n}, where n stands for positive infinity, make up the set of positive integers. Despite being an integer and a whole number, 0 is neither positive nor negative.
The basic calculations employ positive integers. For instance, a store manager needs to employ positive integers and fundamental math to calculate totals when determining the inventory, or how many things the store has. The integers in the set are {...,-3, -2, -1, 0, 1, 2, 3,...}. The group of integers that are strictly greater than zero is known as the positive integer set. As a result, we remove all of the negative integers and 0 from the set of integers, leaving us with the set of numbers {1, 2, 3,...}. The number one is the smallest in the group of numbers {1, 2, 3,…..}.
The smallest positive integer is 1.
Hence, the correct answer is option 3.
