The four pillars of Human Development are Equity, Productivity, Empowerment, and Sustainability.

Option 1, `Equity, inclusion, productivity and empowerment`, is partially true: Equity, productivity and empowerment are indeed pillars of human development. However, inclusion is not considered one of the four pillars, it`s rather an overarching principle of human development.

Option 3, `Productivity, gender, inclusion and equity`, is partially true. As mentioned earlier, productivity and equity are pillars of human development, but gender and inclusion, though significant factors, are not recognized as pillars.

Option 4, `Labour, productivity, inclusion and equity`, is not correct. In this case, though productivity and equity are correct, labour and inclusion are not counted as pillars. Instead, they are under the larger umbrella of the four pillars.

In contrast, Option 2, `Equity, productivity, empowerment and sustainability`, is the correct answer. Each term represents a broad concept that together form the foundation of human development, according to the United Nations Development Program.
