Let's talk about what an adjective phrase is first:
An adjective phrase is a group of words that describe a noun or pronoun in a sentence.
For example:
"The small kitten jumped at the big dog."
"A person smarter than me needs to figure this out."
The adjective phrase can be placed before or after the noun or pronoun in the sentence.
So out of the options listed here, the answer would be "Martin read a book in the early evening."
