Select the Venn diagram that best illustrates the relationship between the following classes.
Ticket, Aeroplane, Rail

Correct option is A

"Aeroplane," and "Rail," let's analyze the relationship between these classes:

Ticket: This is something that allows entry or travel on various modes of transportation, such as an aeroplane or a train (rail).

Aeroplane: This is a mode of transportation that requires a ticket for travel.

Rail: This is another mode of transportation that also requires a ticket for travel.

Relationship:

Both "Aeroplane" and "Rail" are types of transportation, so they do not overlap with each other.

"Ticket" is related to both "Aeroplane" and "Rail" because you need a ticket to travel on either.

Correct answer is (a).
