AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
(a) Both A and R are true, and R is the correct explanation of A.
Deendayal Port (Kandla) was developed soon after Independence specifically to ease trade on Mumbai port due to the loss of Karachi port to Pakistan after Partition.
The textbook directly states: "Deendayal Port (Kandla) was the first port developed soon after Independence to ease the volume of trade on the Mumbai port, in the wake of loss of Karachi port to Pakistan after the Partition." Both the Assertion and Reason are factually correct, and the Reason directly explains why the port was developed — making option (a) the only correct choice.
