Read the passage and answer the questions:
When Cunningham, the first Director-General of the ASI, began archaeological excavations in the mid-nineteenth century, archaeologists preferred to use the written word (texts and inscription) as a guide to investigations. In fact, Cunningham's main interest was in the archaeology of the Early Historic (c. sixth-century BCE-fourth century CE) and later periods. He used the accounts left by Chinese Buddhist pilgrims who had visited the subcontinent between the fourth and seventh centuries CE to locate early settlements. Cunningham also collected, documented and translated inscriptions found during his surveys. When he excavated sites he tended to recover artefacts that he thought had cultural value.

A. Chinese Records
B. Buddhist Inscriptions
C. Mesopotamian Seals
D. Bahrain Weights
