its B, I did the test.

Scholars believe that the Indus Valley had a highly developed civilization based on several factors. One of these factors is the presence of written records. Although the Indus Valley script has not been deciphered yet, many inscriptions have been found on seals and other objects. These inscriptions suggest a system of writing and potentially indicate a high level of literacy within the civilization.

Another reason is the remarkable urban planning exhibited by the cities of the Indus Valley. The cities, such as Mohenjo-daro and Harappa, show evidence of carefully laid out street grids, well-planned residential areas, and sophisticated sewage and drainage systems. The level of organization and engineering required for these urban planning efforts indicates a highly developed civilization.

Religion also played an important role in the Indus Valley civilization, with evidence of highly organized religious practices. Archaeological findings indicate the presence of temples, public bathing areas, statues of deities, and ritual objects. These religious practices suggest a complex belief system and a well-organized religious hierarchy.

Lastly, the royal tombs of the Indus Valley have yielded a significant number of artifacts. These artifacts include jewelry, pottery, figurines, and other objects made from precious materials such as gold, silver, and bronze. The richness and variety of these artifacts suggest a society with skilled artisans, trade networks, and a degree of wealth and social hierarchy.

In conclusion, scholars believe that the Indus Valley had a highly developed civilization based on the presence of written records, the urban planning of its cities, the highly organized religion, and the abundance of artifacts found in its royal tombs.
