The correct answer is D. A thematic map
Explanation:
Thematic maps differ from other types of maps because this displays and explains a specific phenomenon (theme) in relation to the location such as population density, voting preferences, among others. This does not occur in physical maps that show elements such as mountains and rivers or in political maps that focus on boundaries of territories. In this context, this type of map is ideal to study the amount of oil a location produces as this is a specific theme and cannot be found in a physical or political map.
