Here's why:

• Mass communication requires a formal structural organization:

  • Mass media organizations, such as television networks, newspapers, and radio stations, have complex structures with departments like news, production, marketing, sales, and human resources. These departments are interconnected and work together to achieve the organization's goals.

• Mass communication requires a large body of employees:

  • Due to the scale of operations involved in reaching large audiences, mass media organizations typically employ a significant number of people across various roles, including journalists, editors, technicians, sales representatives, and administrative staff.

Why other options are incorrect:

• A. it requires a informal structural organisation: This is incorrect. Mass communication demands a well-defined and structured organization for efficient functioning.
• D. it requires a small body of employee: This is incorrect as mentioned above.
• E. it requires small scale capital: This is not necessarily true. Mass media organizations often require substantial investment in infrastructure, technology, and personnel.
