Explanations:The question revolves around the geographical location of ancient cities in relation to the Arabian Sea and their potential for sea trading routes. The Indus Valley Civilization, one of the world's earliest urban civilizations, flourished in the northwestern regions of the Indian subcontinent, primarily in what is now Pakistan and northwest India. Two of the most prominent cities of this civilization were Mohenjo-Daro and Harappa.
Mohenjo-Daro, which translates to "Mound of the Dead," was located in the Sindh region of present-day Pakistan. It was situated near the Indus River and had a strategic location that allowed it to be relatively close to the Arabian Sea. This proximity made it a likely candidate for having a sea trading route, as it would have been easier to access the sea for maritime trade.
Harappa, on the other hand, was located in the Punjab region of present-day Pakistan. It was further inland compared to Mohenjo-Daro and did not have direct access to the Arabian Sea. Therefore, it would have been less likely to have a sea trading route compared to Mohenjo-Daro.
The Indus Valley Civilization was known for its advanced urban planning, standardized weights and measures, and extensive trade networks. The presence of a sea trading route would have been crucial for the economic prosperity of a city, as it would facilitate trade with distant regions and allow for the exchange of goods and ideas.
Thus, based on the geographical location of the cities, Mohenjo-Daro would be more likely to have a sea trading route using the Arabian Sea. This is why option A is the correct answer.
