Assertion: Cotton Textile industry suffered a major recession after partition.
Reasoning: After partition, most of the good quality cotton growing areas had gone to West Pakistan and India was left with 409 mills and only 29 per cent of the cotton producing area.

Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

By 1947, the number of mills in India went up to 423 but the scenario changed after partition, and this industry suffered a major recession. This was due to the fact that the most of the good quality cotton growing areas had gone to West Pakistan and India was left with 409 mills and only 29 per cent of the cotton producing area.
