Concept:
The Sustainable Development Goals (SDGs) are a set of global goals adopted by the United Nations (UN) in 2015 to achieve a better and more sustainable future by the year 2030.
These goals address:
• Poverty
• Hunger
• Health
• Education
• Gender equality
• Climate action
• Environmental sustainability
There are a total of:
\[
17 \text{ Sustainable Development Goals}
\]
Step 1: Analyze Option A
Option A is:
\[
\text{Good health and well being}
\]
This is officially one of the United Nations Sustainable Development Goals.
Its purpose includes:
• Ensuring healthy lives
• Reducing diseases
• Improving healthcare systems
• Promoting mental and physical well-being
Therefore:
\[
A \text{ is an SDG}
\]
Step 2: Analyze Option B
Option B is:
\[
\text{Zero Hunger}
\]
This is also one of the official SDGs.
Its objectives include:
• Ending hunger
• Improving nutrition
• Achieving food security
• Promoting sustainable agriculture
Thus:
\[
B \text{ is an SDG}
\]
Step 3: Analyze Option C
Option C is:
\[
\text{Gender Equality}
\]
This is another important Sustainable Development Goal.
Its purpose includes:
• Equal rights for all genders
• Women empowerment
• Elimination of discrimination
• Equal educational and employment opportunities
Hence:
\[
C \text{ is an SDG}
\]
Step 4: Analyze Option D
Option D is:
\[
\text{Space research}
\]
Although space research is scientifically important and contributes to technological advancement, it is not included among the official 17 Sustainable Development Goals established by the United Nations.
Therefore:
\[
D \text{ is NOT an SDG}
\]
Step 5: Final Conclusion
Among the given options, the one which is not a Sustainable Development Goal is:
\[
\boxed{\text{Space research}}
\]
Hence, the correct option is:
\[
\boxed{(D)}
\]
