Mariamma Festival

The correct answer is Option (4) → Mariamma Festival

While Bihu, Pongal, and Ugadi festivals are closely associated with agricultural cycles and harvests, the Mariamma Festival does not have a direct connection to agrarian activities. Instead, it is primarily a Hindu festival celebrated to honor the goddess Mariamman, who is believed to protect villages from diseases and epidemics.
