The correct answer is option 'B' (SDG 12).

Explanation:
The Sustainable Development Goals (SDGs) are a set of 17 global goals adopted by the United Nations in 2015 to achieve a more sustainable future for all. Each goal has specific targets and indicators to monitor progress.

1. Lifestyle Material Footprint:
- The lifestyle material footprint refers to the amount of natural resources consumed and waste generated by individuals or households as a result of their consumption patterns and lifestyle choices.
- This includes the use of energy, water, raw materials, and the generation of waste and emissions.
- It is important to reduce our material footprint to minimize the negative impact on the environment and promote sustainable consumption and production patterns.

2. Food Wastage:
- Food wastage refers to the loss or wastage of food throughout the supply chain, from production to consumption.
- It includes food that is discarded or spoiled during production, transportation, storage, and consumption.
- Food wastage has significant social, economic, and environmental implications, including hunger, increased greenhouse gas emissions, and wasted resources.
- Target 12.3 of SDG 12 aims to halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains by 2030.

3. Plastic Waste:
- Plastic waste refers to the accumulation of plastic materials that are discarded and not recycled or properly disposed of, leading to environmental pollution.
- Plastic waste is a major environmental issue as it takes hundreds of years to decompose and can harm wildlife, ecosystems, and human health.
- SDG 12 includes targets to prevent and significantly reduce marine pollution of all kinds, including plastic waste, by 2025.

4. Sustainable Tourism:
- Sustainable tourism refers to tourism that takes full account of its current and future economic, social, and environmental impacts.
- It involves minimizing negative impacts on the environment and local communities, while maximizing the benefits for the host destination.
- SDG 12 has a target to promote sustainable tourism and create jobs and opportunities for local communities, while conserving natural and cultural heritage.

Therefore, the mentioned targets of lifestyle material footprint, food wastage, plastic waste, and sustainable tourism align with SDG 12, which focuses on ensuring sustainable consumption and production patterns.
