Answer Options

A. Rainfall mean = 50.00 mm, SD = 38.55 mm; Temperature mean = 30.33 °C, SD = 2.00 °C; CV_R ≈ 77.0 %, CV_T ≈ 6.6 %; Rainfall is more variable; September is most drought‑prone.
B. Rainfall mean = 45.00 mm, SD = 35.00 mm; Temperature mean = 30.33 °C, SD = 2.32 °C; CV_R ≈ 77.8 %, CV_T ≈ 7.6 %; Temperature is more variable; August is most drought‑prone.
Correct Answer C. Rainfall mean = 47.33 mm, SD = 38.55 mm; Temperature mean = 30.33 °C, SD = 2.32 °C; CV_R ≈ 81.5 %, CV_T ≈ 7.6 %; Rainfall is more variable; July is most drought‑prone.
D. Rainfall mean = 47.33 mm, SD = 40.00 mm; Temperature mean = 31.00 °C, SD = 2.50 °C; CV_R ≈ 84.6 %, CV_T ≈ 8.1 %; Rainfall is more variable; June is most drought‑prone.
