Answer 1

1. The correct graph for Chennai is Graph E.
2. Three Reasons: 
   1. Temperature: 
      • Chennai has high temperatures throughout the year (around 25°C to 30°C) because it is a coastal city.
      • Graph E shows high and stable temperatures all year.
   2. Amount of Rainfall:
      • Chennai receives around 125 cm of rainfall.
      • Graph E shows moderate to high rainfall, matching this pattern.
   3. Rainfall Regime:
      • Chennai gets most of its rain in October-November due to the Northeast Monsoon (retreating monsoon).
      • Graph E shows a peak in rainfall during these months, which matches Chennai’s rainfall pattern.
