Topic: Benefits of E-Retailing
Step 1: Understanding the Question:
Identify a positive feature of selling online from the perspective of the business owner (retailer).
Step 2: Detailed Explanation:
Physical stores have opening and closing hours. However, an online store (e-retail) is always open.
This "24/7 accessibility" (Option C) allows customers to shop at their convenience, even late at night, leading to higher potential sales.
Options A, B, and D are actually the opposite of e-retailing's true nature (it usually has lower overheads, global reach, and vast product variety).
Step 3: Final Answer:
The main advantage is 24/7 accessibility.
Final Answer: 24/7 accessibility.
