The correct answer is option 'C' - England.

Industrialization refers to the process of transforming an agrarian-based society into one that is based on industry and manufacturing. It involves the widespread use of machinery, the establishment of factories, and the development of new technologies.

England, also known as Great Britain, was the pioneer country in industrialization. During the 18th and 19th centuries, England experienced a significant transformation in its economic and social structure, known as the Industrial Revolution. This period marked the shift from an agricultural society to an industrial one.

Factors that contributed to England's status as the pioneer country in industrialization include:

1. Natural Resources:
- England had abundant natural resources, such as coal and iron ore, which were essential for industrial production.
- Coal was used as a source of energy for steam engines, while iron ore was used in the production of machinery and infrastructure.

2. Colonial Empire:
- England had a vast colonial empire that provided access to raw materials and markets.
- The colonies supplied England with resources like cotton, rubber, and spices, which were crucial for industrial production.

3. Agricultural Revolution:
- Prior to the Industrial Revolution, England experienced an Agricultural Revolution that increased agricultural productivity.
- Innovations in farming techniques, such as crop rotation and selective breeding, led to higher crop yields and a surplus of food.
- This surplus allowed for a population increase, providing a larger labor force for the emerging industries.

4. Technological Innovations:
- England was at the forefront of technological innovations during the Industrial Revolution.
- Inventions such as the spinning jenny, steam engine, and power loom revolutionized the textile industry.
- The development of new machinery and manufacturing processes greatly increased productivity and efficiency.

5. Capital and Investment:
- England had a well-developed banking system and access to capital from wealthy individuals.
- This allowed for the financing of new industries and the construction of factories and infrastructure.

Overall, England's combination of natural resources, colonial empire, agricultural advancements, technological innovations, and access to capital made it the pioneer country in industrialization. The Industrial Revolution in England served as a model for other countries to follow, leading to widespread industrialization across the world.
