A vegetation type requires a mean annual temperature between 15 °C and 20 °C and at least 1 200 mm of annual rainfall. Sea‑level temperature is 30 °C and decreases at a lapse rate of 6.5 °C per 1 000 m. Rainfall at sea level is 1 900 mm. Rainfall decreases at 0.4 mm per metre for the first 800 m of altitude and at 0.6 mm per metre above 800 m. Determine whether any altitude on the mountain satisfies both the temperature and rainfall requirements, and state the result.

Answer Options

Correct Answer A. No suitable altitude; the required temperature range occurs above the altitude where rainfall falls below 1200 mm.
B. Yes, an altitude of about 1 200 m satisfies both the temperature and rainfall requirements.
C. Yes, altitudes between 800 m and 1 000 m meet both the temperature and rainfall criteria.
D. No suitable altitude; the temperature range is met, but rainfall remains above 1200 mm at all relevant elevations.
