Answer:
Trochaic
Step-by-step explanation:
In poetry, an iamb is a metrical foot (a group of two or three syllables) that has one unstressed syllable followed by a stressed syllable (It can be exemplified with the sound daDUM). As for a trochee, it is a metrical foot consisting of one stressed syllable followed by an unstressed syllable (DUMda)
All four words are trochaic as each word has two syllables, with the first syllable being a stressed one, and the second being an unstressed syllable.
