A line graph displays the monthly revenue (in thousands of USD) for two competing smartphone models, 'Alpha' and 'Beta', from January to December of the current year. Alpha's revenue starts at $150K in January and steadily increases to $280K by December. Beta's revenue starts at $200K in January, peaks at $250K in April, then declines to $180K by December. In how many months did Alpha's revenue exceed Beta's revenue?
✓ Correct Answer: Option D
Alpha's revenue is 150 (Jan) to 280 (Dec) (linear approx: slope ~11.8). Beta's revenue is 200 (Jan), 250 (Apr), 180 (Dec). Alpha overtakes Beta roughly mid-year and stays ahead. Closer inspection shows Alpha's revenue exceeds Beta's for 6 months (July-December).
