The correct answer is D. A text in which the writer has provided enough information in the sentence or surrounding sentences that the meaning of the word is clear.
Explanation:
In texts and in the reading process, context clues strategy is about using the words, details, and sentences in which an unknown or unfamiliar word appears in order to determine the meaning of it. This strategy is quite useful as in this way the reader can understand all the information in a text without using an external source such as a dictionary or any other strategy.
However, this strategy can only be used if the author or writer of a text provides details, words or similar that describe or give clues that clarify the meaning of the unknown word. Considering this, it can be concluded the situation in which you can use successfully this strategy is "a text in which the writer has provided enough information in the sentence or surrounding sentences that the meaning of the word is clear" because this strategy relies on the clues or hints provided by the words and sentences that surround an unknown word but without hints this strategy cannot be used.
