Assertion:. There is strong relationship between raw material and type of industry.
Reasoning: It is economical to locate the manufacturing industries at a place where cost of production and delivery cost of manufactured goods to consumers are the least.

Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

Location of industries is influenced by several factors like access to raw materials, power, market, capital, transport and labour, etc. Relative significance of these factors varies with time and place. There is strong relationship between raw material and type of industry. It is economical to locate the manufacturing industries at a place where cost of production and delivery cost of manufactured goods to consumers are the least.

Assertion: There is a strong relationship between raw material and type of industry.

True. The type of industry is often directly determined by the availability and accessibility of raw materials. For example, steel industries are typically located near iron ore and coal deposits, while paper mills are often found near forests.

Let's analyze the assertion and reasoning individually:

Assertion: There is a strong relationship between raw material and type of industry.

True. The type of industry is often directly determined by the availability and accessibility of raw materials. For example, steel industries are typically located near iron ore and coal deposits, while paper mills are often found near forests. This relationship exists because:

Reasoning: It is economical to locate the manufacturing industries at a place where the cost of production and delivery cost of manufactured goods to consumers are the least.

The reasoning directly supports the assertion. Minimizing production and delivery costs is essential for any industry to remain competitive. By locating near raw materials, industries can reduce transportation costs, which are a significant component of production costs. Additionally, being closer to markets (consumers) can also reduce delivery costs and improve efficiency.
