  1. 125

  2. 165

  3. 145

  4. 135

D Correct answer
Explanation

The area of the circular path equals the area of the outer circle minus the area of the inner garden. Inner radius is 21 m, outer radius is 21+3=24 m. Area = π(R² - r²) = π(24² - 21²) = π(576 - 441) = 135π m². Option D correctly shows 135.
