What does the term covert imply regarding terrorist activities?

The term "covert" refers to actions or operations that are intentionally concealed or kept from public knowledge. In the context of terrorist activities, this implies that these operations are conducted in a secretive manner, often to avoid detection by law enforcement or intelligence agencies. Covert operations are characterized by the use of deception and stealth to achieve strategic objectives without revealing the perpetrator's identity or intentions.

In contrast, options indicating open and public operations, broadly acknowledged movements, or public awareness campaigns suggest transparency and visibility, which are contrary to the inherent nature of covert activities. By maintaining a hidden profile, those who engage in covert actions aim to evade countermeasures and maintain the element of surprise, making 'secretive and hidden operations' the most fitting definition of the term in this context.
