All the provided sentences contain both a noun phrase and a verb phrase. However, if you need to choose one, let's analyze them:
A. Noun Phrase: "frogs and insects"; Verb Phrase: "can find by the pond if you look closely enough."
B. Noun Phrase: "The pigeons"; Verb Phrase: "have not landed on my neighbor’s balcony in a long time."
C. Noun Phrase: "Some dog breeds"; Verb Phrase: "have docked tails."
D. Noun Phrase: "my grandmother’s favorite armchair"; Verb Phrase: "He sat on."
All four sentences qualify, but for a strong example, A is good as it contains both the subject and the action with a location. However, any of the options could correctly illustrate the concept if needed.
