Concept:The sentence requires a verb in the passive voice to describe an anticipated situation in the present tense.
Explanation:The sentence reports that newspapers have mentioned heavy flooding.
The damage is something that is anticipated to be extensive.
The correct verb form must be passive because the damage does not perform the action of expecting – it is the object of expectation.
In present tense, the passive construction uses “is” + past participle.
Thus, “is expected” fits perfectly: “The damage is expected to be extensive.”
Option A, “expected,” is missing a helping verb and is incomplete.
Option B, “is expecting,” is active voice, which is wrong because the damage cannot expect something.
Option C, “has been expected,” is present perfect passive and implies a completed action, but the context here is a current, ongoing report of an anticipated situation, so simple present passive is needed.
Only option D, “is expected,” provides the correct grammatical structure and meaning.
Answer:D. is expected
