Step 1: Understanding the Question: 
The question asks for the purpose for which fixed capital is required. 
 Step 2: Key Concept: 
There are two main types of capital in a business: 
    
 Fixed Capital: The capital invested in acquiring long-term assets (fixed assets) that are used for more than one year and are not meant for resale. Examples include land, buildings, plant, and machinery. 
    
 Working Capital: The capital used to finance day-to-day operations. It is used for short-term assets like inventory (stock), accounts receivable, and for paying routine expenses and short-term liabilities. 
 Step 3: Detailed Explanation: 
Let's analyze the options based on this distinction: 
    
 (A) Payment of routine expenses: These are day-to-day operational costs (like salaries, rent) and are met using working capital. 
    
 (B) Purchase of land: Land is a fixed asset, a long-term investment. Its purchase requires fixed capital. 
    
 (C) Purchasing stock (inventory): Stock is a current asset. It is part of the operating cycle and is financed by working capital. 
    
 (D) Payment to creditors: Creditors are current liabilities. Paying them is part of managing working capital. 
 Step 4: Final Answer: 
Fixed capital is specifically used for acquiring fixed assets like land. Therefore, (B) is the correct answer.
