WRETCHED:

Wretched -> very unhappy/miserable; in a very bad condition

Option 1 → "Poor" - CORRECT: best matches wretched as it can mean both unfortunate/miserable AND in bad condition

Option 2 → "Foolish" (lacking good judgment) - completely different meaning

Option 3 → "Insane" (mentally ill) - unrelated to being miserable

Option 4 → "Strained" (tense/stretched) - different context and meaning$

$"Poor" captures both aspects of wretched: being in a miserable state and bad condition.
