Consider the following statements regarding the radiocarbon dating and chronology of the Indus Valley Civilization:\n1. D.P. Agrawal was among the first to systematically use Radiocarbon (C-14) dating to propose a shorter chronology (c. 2300–1750 BCE) for the Mature Harappan phase.\n2. MASCA (Museum Applied Science Center for Archaeology) calibration of radiocarbon dates pushed back the timeline of the Mature Harappan phase to approximately 2600–1900 BCE.\n3. The early Harappan phase at Bhirrana has yielded some of the oldest radiocarbon dates, pushing the origins of the Hakra culture back to the 8th millennium BCE.\nWhich of the statements given above are correct?
Options:
- A: 1 and 2 only
- B: 2 and 3 only
- C: 1 and 3 only
- D: 1, 2 and 3
