The correct answer is: A. 4 BC
Jesus Christ was crucified in 33 AD, according to the most widely accepted dating system, the Anno Domini calendar. This calendar was established by Dionysius Exiguus in 525 AD, and it is based on the assumption that Jesus was born in the year 1 AD. However, there is no historical evidence to support this assumption, and many scholars believe that Jesus was actually born several years earlier.
The year 4 BC is the most likely date for Jesus’ crucifixion, according to a number of historical and astronomical factors. For example, the Gospel of Luke states that Jesus was born during the reign of Herod the Great, who died in 4 BC. Additionally, a lunar eclipse that is mentioned in the Gospel of Matthew is believed to have occurred on January 8, 4 BC.
The other options are incorrect because they are not supported by historical evidence. Option B, 4 AD, is the year that is traditionally given for Jesus’ crucifixion, but there is no evidence to support this date. Option C, 20 AD, is the year that is given for Jesus’ crucifixion by some scholars, but this date is also not supported by historical evidence. Option D, 1 AD, is the year that is given for Jesus’ birth by Dionysius Exiguus, but there is no evidence to support this date.
In conclusion, the most likely date for Jesus’ crucifixion is 4 BC. This date is supported by a number of historical and astronomical factors.
