The correct answer is Nhava Sheva and Haldia.

Satellite ports are smaller ports that are strategically located to support and reduce the burden on a major port. They act as extensions of the main port, handling some of the cargo traffic and facilitating efficient movement of goods. This reduces congestion and improves overall port efficiency. Nhava Sheva and Haldia are designated as satellite ports in India's port system. They play a crucial role in supporting the larger, main ports, easing congestion and enhancing the overall logistics infrastructure. Other options listed include major ports in their own right, not acting in a satellite capacity to another larger port.

The selection of satellite ports is a complex process that considers factors like proximity to the main port, existing infrastructure, cargo handling capacity, and overall economic viability. Effective satellite port implementation leads to significant economic benefits, improved efficiency in cargo handling, and optimized logistics within a region. Choosing the right location requires careful analysis of various logistical and economic factors to ensure efficient functioning.
