Correct Answer:
C. Anno Domini
The term AD is part of a widely used dating system, often paired with BC (Before Christ), to denote years in the Gregorian calendar. Understanding its origin and meaning is fundamental to historical chronology.
- The correct answer is Anno Domini. AD stands for the Latin phrase 'Anno Domini', which translates to 'in the year of the Lord'. This system traditionally counts years from the birth of Jesus Christ, marking the beginning of the Christian era.
- After Demonstration is an incorrect and fabricated phrase.
- After Death is a common misconception. AD does not refer to the period after Christ's death but rather the years following his birth. The period before his birth is denoted by BC.
- Signed by King John is entirely unrelated to the meaning of AD.
