The following are developments during the Import Substitution Period, except one.a.Policy interest shifted from import to export promotionb.Regions interacting among themselves more closelyc. Formal cutting of close ties between US and Philippines on July 4, 1946d.High localization index (except for agriculture) for all industries particularly for NCR (construction and utilities sector)

During the Import Substitution Period, several developments took place. Let's analyze each option to identify the one that does not belong:

a. Policy interest shifted from import to export promotion: This is a development that occurred during the Import Substitution Period. The focus shifted from importing goods to promoting exports as a means of boosting the economy.

b. Regions interacting among themselves more closely: This is also a development that took place during the Import Substitution Period. As the country aimed to reduce its dependence on imports, regions started to collaborate more closely to strengthen their local industries.

c. Formal cutting of close ties between US and Philippines on July 4, 1946: This is a significant event that happened during the Import Substitution Period. It marked the end of the colonial relationship between the United States and the Philippines, allowing the country to pursue its own economic policies.

d. High localization index (except for agriculture) for all industries particularly for NCR (construction and utilities sector): This is another development that occurred during the Import Substitution Period. The localization index refers to the degree of local production and consumption within an industry. The high localization index, especially in the construction and utilities sector in the National Capital Region (NCR), indicates a reduced reliance on imported goods.

Based on the analysis, the option that does not belong is a. Policy interest shifted from import to export promotion.
