Final answer:
Consistent size of bricks in many areas suggests a unified construction industry, pointing to the existence of a centralized government that imposed standardization in construction practices.
Step-by-step explanation:
Why would having the same size of bricks in many areas suggest there was a government in Ancient India? The answer is B) Because consistent brick sizes suggest a unified construction industry. This indicates a level of standardization and central control likely imposed by a governing body which coordinated construction activities across different regions, ensuring that the common building materials like bricks conformed to specific standards. Such uniformity in construction practices was important for the efficient management of resources and infrastructure development. This is evident in civilizations such as Babylon and the Indus Valley, where the use of uniform bricks made from local materials like mud or clay was commonplace for building durable structures. The harmonized sizes of bricks across large areas reflect the presence of administrative measures to regulate building materials and techniques, which is often a function of governance.
