Why does the need for cyber security increase?

Correct answer: Because digital data and online transactions increase

The governing concept is that technological progress creates both business opportunities and security risks. As companies and customers use more websites, cloud systems, digital records, and online payments, more valuable information moves through electronic networks. This increases exposure to unauthorised access, fraud, data theft, and service disruption, so stronger cyber security becomes necessary. Therefore, option D is correct. Scarcity of raw material, changing weather, and the arrival of festivals may affect business in other ways, but none of them directly explains the growing need to protect digital data and online transactions.
