Thus option a. High-level reconnaissance. is correct answer.
Step-by-step explanation:
"High-level reconnaissance" is another term for footprinting in the context of cybersecurity and information gathering. Footprinting involves collecting information about a target system or network to identify potential vulnerabilities and gather intelligence.
High-level reconnaissance refers to the initial phase of information gathering, where broad and general data is collected about the target without directly interacting with the system.
This information can then be used to plan further, more targeted attacks or assessments.
Thus option a. High-level reconnaissance. is correct answer.
