Concept:
In logic and linguistics, "denotation" refers to the set of objects to which a term applies. Arranging terms in increasing denotation means moving from the most specific category (which contains the fewest members) to the most general category (which contains the largest number of members).
Step 1: Analyzing the categories from specific to general.
1. Sedan (D): A specific type of car. This is the most restrictive category.
2. Car (B): A broader category that includes Sedans, SUVs, Hatchbacks, etc.
3. Four wheeler (E): A broader category including cars, trucks, and vans.
4. Automobile (C): Includes all motorized vehicles used for transport.
5. Machine (A): The most general category, encompassing everything from simple levers to complex engines and computers.
Step 2: Finalizing the Sequence.
The sequence of increasing denotation (Specific $\rightarrow$ General) is D $\rightarrow$ B $\rightarrow$ E $\rightarrow$ C $\rightarrow$ A.
