Option d is the correct answer. The spirit of Christians behind the festival of Easter is the day of Resurrection of Christ. Easter is a Christian festival and cultural holiday that commemorates the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day after his crucifixion by the Romans at Calvary. It is the culmination of the Passion of Jesus Christ, preceded by Lent, a 40 -day period of fasting, prayer, and penance, and followed by Eastertide, a 50 -day period of celebration and joy. Easter is the most important festival in the Christian calendar, and is celebrated by thousands of people all over the world.
