Which of the diagram below represents the statement. if it is an insect then it has wings

The diagram that represent the statement is a Venn diagram in which:

An inner circle labeled "insects" is completely included inside an outer circle which is labeled "has wings".

In such diagram all the insects are inside the bigger set of things that have wings. That means that all the insects have wings but not all the things that have wings are insects.

That is exactly what the proposition if it is an insect then it has wings.

As per the proposition, having wings is a necessary condition to be insect, but it is not sufficient.
