This question asks us to identify the correct statements about targets associated with specific Sustainable Development Goals (SDGs).

Analyzing SDG Targets

Let's examine each statement:

• Statement A: Target under SDG8 is to sustain 7% GDP in least developed countries

  This statement refers to SDG 8, which focuses on Decent Work and Economic Growth. Target 8.1 specifically aims to "sustain per capita economic growth in accordance with national circumstances and, in particular, at least 7 per cent gross domestic product growth per annum in the least developed countries" by 2030. Thus, statement A is correct.

• Statement B: Target under SDG3 is to ensure universal access to sexual and reproductive health care by 2030

  This relates to SDG 3, Good Health and Well-being. Target 3.7 aims to "ensure universal access to sexual and reproductive health-care services, including for family planning, information and education" by 2030. Therefore, statement B is correct.

• Statement C: Target under SDG4 is to ensure equal access for all women and men to affordable quality higher education by 2030

  This concerns SDG 4, Quality Education. Target 4.3 states the goal is to "ensure equal access for all women and men to affordable and quality technical, vocational and tertiary education, including university education" by 2030. Higher education is encompassed within tertiary education, making statement C correct.

• Statement D: Target under SDG7 is to build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation

  This statement describes goals related to building infrastructure, industrialization, and innovation. These are key components of SDG 9 (Industry, Innovation and Infrastructure), particularly targets like 9.1, 9.2, and 9.5. SDG 7 focuses on Affordable and Clean Energy. Since the described targets do not align with SDG 7, statement D is incorrect.

• Statement E: Target under SDG6 to improve water quality by reducing pollution by 2030

  This refers to SDG 6, Clean Water and Sanitation. Target 6.3 aims to "improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally" by 2030. Statement E accurately reflects this target, making it correct.

Conclusion on Correct Statements

Based on the analysis, statements A, B, C, and E are correct. Statement D is incorrect as it pertains to SDG 9, not SDG 7.

Therefore, the correct option includes A, B, C, and E only.
