The second phase of land reforms in Pakistan, enacted in 1977 under the Land Reforms Act, limited individual landholdings to 100 acres of irrigated land (and 200 acres of unirrigated land), with an overall ceiling of 8,000 Produce Index Units (PIU). This is a reduction from the previous ceiling of 150 acres irrigated land in the 1972 reforms. Therefore, the correct answer is not 50 acres but 100 acres, making option C the closest correct choice. However, since 100 acres is option C and 50 acres is option A, the original answer A is incorrect. The question options do not include 100 acres as the correct limit for the second phase, so the correct answer should be C. The explanation has been updated accordingly.

The option 'Chakala' in the question appears to be a misspelling of 'Chaklala', which is near Rawalpindi but is no longer the location of the headquarters.
