identify the choice that best answers the question.

taylor’s fifth - grade class took a field trip to the delaware river and learned about its ecosystem.
a. fifth - grade class
b. field trip
c. delaware river
d. ecosystem

Explanation:

Proper nouns name specific unique entities, such as specific geographic features. The Delaware River is a particular river, so it is a proper noun and requires capitalization of both its specific name and the generic "River" term. The other options are common nouns referring to general groups, activities, or concepts, not specific unique entities.

Answer:

C. delaware river
