30. Laws can help endangered species by prohibiting

A. Captive breeding
B.habitat preservation
C diversity of genes
D. products made from the species

I got D, I have a feeling that this may be wrong.

D is right.

Sorry, my bad. D is not right, it is B.

To determine the correct answer, let's analyze each option:

A. Captive breeding: Captive breeding refers to breeding endangered species in controlled environments to increase their population. While it may seem counterintuitive, prohibiting captive breeding can be beneficial in some cases. This prevents the exploitation of animals for commercial purposes and ensures the focus is on preserving their natural habitats.

B. Habitat preservation: This option refers to the conservation and protection of natural habitats where endangered species live. It is widely recognized as one of the most effective ways to safeguard endangered species and promote their recovery. Laws that enforce habitat preservation can restrict activities like deforestation, urbanization, and other forms of habitat destruction.

C. Diversity of genes: Maintaining genetic diversity is crucial for the long-term survival of endangered species. If a population lacks genetic diversity, it becomes more vulnerable to diseases, environmental changes, and other threats. While laws can indirectly impact genetic diversity through habitat preservation or captive breeding regulations, directly prohibiting diversity of genes is not a commonly used approach.

D. Products made from the species: Prohibiting products made from endangered species prevents their exploitation, such as hunting or trading for their body parts, skins, or other products. This approach aims to reduce demand and eliminate the commercial incentive behind exploiting endangered species.

Considering the above analysis, option B, habitat preservation, seems to be the most appropriate answer. Laws that require habitat preservation play a fundamental role in protecting endangered species by safeguarding their natural habitats from destruction or degradation.

Therefore, the correct answer is B. habitat preservation.
