Globalisation has had a significant impact on indigenous craft and literary traditions, with option C stating that it threatens many of these traditions. This answer can be supported by several key factors:

1. Loss of Traditional Knowledge:
- Globalisation often promotes standardized and mass-produced goods, which can lead to a decline in demand for traditional indigenous crafts. As a result, the younger generation may lose interest in learning these crafts, leading to a loss of traditional knowledge and skills.

2. Economic Pressures:
- Indigenous artisans and craftsmen may face economic pressures as globalisation introduces cheaper and more easily accessible alternatives. This can result in a decline in the production and sale of traditional crafts, leading to financial difficulties for indigenous communities.

3. Homogenization of Culture:
- Globalisation tends to promote a homogenization of culture, where dominant global trends and tastes overshadow indigenous traditions. This can result in a loss of cultural diversity and uniqueness, as indigenous crafts and literature may be replaced by more popular and commercially-driven forms.

4. Appropriation and Exploitation:
- Globalisation can also lead to the appropriation and exploitation of indigenous crafts and literary traditions. Indigenous designs, motifs, and stories may be appropriated by mainstream industries without proper recognition or compensation, leading to cultural exploitation and erosion of indigenous identity.

5. Language Shift:
- Globalisation often promotes the dominance of major languages, leading to a decline in the use and preservation of indigenous languages. This can have a significant impact on indigenous literary traditions, as many oral stories and cultural knowledge are passed down through generations in indigenous languages.

6. Cultural Marginalisation:
- Globalisation tends to prioritize mainstream cultural expressions and values, often marginalizing indigenous cultures and their artistic traditions. This can lead to a loss of visibility and recognition for indigenous crafts and literature, further threatening their survival.

Overall, the impact of globalisation on indigenous craft and literary traditions is not neutral. It poses significant challenges and threats to the preservation and continuation of these traditions, making option C the correct answer.
