Read the passage below carefully and answer the question that follows.
For centuries, the traditional indigo dyeing pits of Northern Nigeria, particularly those in Kano, served not merely as hubs of textile manufacturing but as vital repositories of indigenous chemical knowledge and guild-based economic self-reliance. Craftspeople utilized organic indigo plants (*Indigofera tinctoria*), wood ash lye, and fermented subterranean vats to produce deep, lightfast blue fabrics that signified status, identity, and prestige across Trans-Saharan trade routes. However, the contemporary deluge of cheap, mass-produced synthetic textiles and imported chemical dyes has driven this historic craft to the brink of commercial collapse. Modern market dynamics prioritize rapid, low-cost output over the labor-intensive, multi-week fermentation processes required by organic vats. Consequently, younger generations increasingly abandon guild apprenticeships for immediate urban employment, threatening the intergenerational transmission of ethnobotanical expertise. While some cultural preservationists advocate for tourist-oriented artisanal heritage status, such museumification fails to address the underlying economic viability of the craft. To survive, traditional indigo dyeing requires a systematic integration into contemporary sustainable fashion supply chains, underpinned by protective intellectual property frameworks for indigenous designs and targeted state subsidies for natural raw materials. Without structural economic interventions that bridge historical craftsmanship with modern market utility, these ancient dyeing pits risk becoming static historical relics rather than dynamic engines of local creative economy.
Which of the following best summarizes the central argument of the passage?
- The long-term survival of traditional indigo dyeing depends on structural economic integration and policy support rather than mere heritage preservation.Answer
- BThe labor-intensive multi-week fermentation process of natural indigo dyeing is the primary cause of its economic obsolescence.
- CEstablishing tourist-oriented artisanal heritage sites offers the most practical path to preserving traditional dyeing pits.
- DThe total demise of Trans-Saharan trade routes has forced younger generations to abandon traditional dyeing apprenticeships.
