Step 1: Understanding the Concept:
The Harappan Civilization, also known as the Indus Valley Civilization, is renowned for its advanced urban planning, which is a key feature that distinguishes it from other contemporary civilizations.
Step 2: Detailed Explanation:
Let's analyze each statement:
a) The drainage system was simple and unplanned: This is incorrect. The Harappan drainage system was one of the most sophisticated in the ancient world. It was well-planned, with drains from houses connected to larger street drains, all covered and equipped with manholes for cleaning.
b) The most characteristic element was the development of urban centres: This is correct. The Harappan civilization was primarily an urban culture. Cities like Harappa and Mohenjo-daro were meticulously planned urban centers with advanced infrastructure.
c) The settlement is divided into two sections as the Citadel and Lower Town: This is correct. Most Harappan cities were divided into at least two parts: the Citadel, a smaller, higher area likely used for public buildings and administrative or religious functions, and the Lower Town, a larger area for residential housing.
d) Roads were not based on grid pattern: This is incorrect. The streets in Harappan cities were laid out in a grid pattern, intersecting at right angles, which indicates a high level of planning.
Step 3: Final Answer:
Based on the analysis, statements (b) and (c) are correct descriptions of Harappan culture. Therefore, the correct option is (iii) in the original image, which corresponds to option (C).
