Select the correct answer from the codes given below :

Sustainable Development Goal 4 (SDG 4) aims to "ensure inclusive and equitable quality education and promote lifelong learning opportunities for all." The targets under this goal include:

• Target 4.1: By 2030, ensure all girls and boys complete free, equitable, and quality primary and secondary education (supporting Statement 1).
• Target 4.a: Build and upgrade education facilities that are child, disability, and gender sensitive (supporting Statement 2 regarding infrastructure).

Statement 3 (Agricultural programmes) is central to SDG 2 (Zero Hunger). Statement 4 (Investment in technology) is a broad objective primarily associated with SDG 9 (Industry, Innovation, and Infrastructure). While technology supports education, it is not listed as a primary measure for Goal 4 in the same specific capacity as free education and school infrastructure. Therefore, statements 1 and 2 are the most accurate measures for Goal 4.
