Which one of the following was the official theme of World Soil Day in 2017?

Introduction / Context:
World Soil Day is an annual observance that aims to raise awareness about the importance of healthy soils for food security, climate regulation, and sustainable development. Each year, a specific theme is chosen to highlight a key message about soil conservation. The year 2017 had a unique theme that linked caring for the planet directly with caring for the soil beneath our feet. This question asks learners to select that exact theme from among several realistic sounding alternatives.

Given Data / Assumptions:

• The observance is World Soil Day, celebrated on 5 December each year.
• The question is specifically about the theme for 2017.
• The options list multiple themes used for World Soil Day in different years, plus another related slogan.
• Only one option is the official theme for 2017.

Concept / Approach:
The correct theme for World Soil Day 2017 was Caring for the Planet starts from the Ground. This phrase emphasises that protecting soil resources is a fundamental step in caring for the entire planet, because soil health influences food production, water quality, biodiversity, and climate. The other themes listed in the options either belong to different years or represent related but distinct campaigns. The key to answering correctly is to match the exact wording to the correct year.

Step-by-Step Solution:
Step 1: Recall that World Soil Day themes often include words like soils, life, ground, and planet.Step 2: From study notes or current affairs material, remember that in 2017 the theme connected care for the planet with care for the ground, summarised as Caring for the Planet starts from the Ground.Step 3: Compare this remembered phrase with the options provided.Step 4: Identify Caring for the Planet starts from the Ground as option B.Step 5: Select option B as the correct answer and reject the other options as themes from other years.

Verification / Alternative check:
Official communications from the Food and Agriculture Organization of the United Nations and national agricultural departments for 2017 clearly show the theme Caring for the Planet starts from the Ground printed on banners, posters, and campaign material. Articles discussing World Soil Day 2017 also repeatedly highlight this phrase. The other options in the list appear as themes in different editions of World Soil Day, but not for 2017.

Why Other Options Are Wrong:
Soils and pulses, a symbol for life: This theme was used in a different year and focused particularly on the relationship between soils and pulse crops.

Soils, a solid ground for life: Another authentic theme used in an earlier edition of World Soil Day but not associated with 2017.

Soils, foundation for family farming: This theme highlighted the role of soils in supporting smallholder and family farms and also belongs to another year.

Keep soil alive, protect soil biodiversity: This phrase has been used in later campaigns that focus on soil biodiversity, not the 2017 observance.

Common Pitfalls:
Because all the options are real or very plausible soil related themes, candidates may easily confuse which phrase corresponds to which year. To avoid this, learners should build a short list pairing themes with years for key observances like World Soil Day, World Environment Day, and World Water Day. Remembering that 2017 soil campaigns stressed caring for the planet from the ground up makes it easier to associate that year with the phrase Caring for the Planet starts from the Ground.

Final Answer:
Caring for the Planet starts from the Ground
