Explanations:The question asks which port in Karnataka is known as the gateway of Karnataka. To understand this, we need to consider the geographical and economic significance of the ports in Karnataka. The term "gateway" in this context refers to the primary port that serves as a major entry and exit point for trade and commerce in the state.
New Mangalore Port, located in the district of Dakshina Kannada, is the largest and most significant port in Karnataka. It is situated on the western coast of India and is a crucial economic hub for the state. The port handles a significant amount of cargo, including iron ore, coal, and other goods, making it a vital link for the state's trade activities. Due to its strategic location and economic importance, New Mangalore Port is often referred to as the gateway of Karnataka.
Other ports in Karnataka, such as Bhatkal and Karwar, are smaller and do not have the same level of significance in terms of trade and commerce. Bhatkal port, for example, is a minor port that primarily serves local fishing communities and small-scale trade. Similarly, Karwar port is another minor port that does not have the same level of economic importance as New Mangalore Port.
Mumbai Port, mentioned in one of the options, is located in the state of Maharashtra, not Karnataka. Therefore, it is not relevant to the question of which port in Karnataka is known as the gateway of Karnataka.
In summary, New Mangalore Port is the correct answer because it is the largest and most significant port in Karnataka, serving as a major gateway for trade and commerce. Its strategic location and economic importance make it the primary port through which a significant portion of the state's trade passes.
