1st a,b,c because of (The Information Security Triad: Confidentiality, Integrity, Availability ) and authorization means giving permission for something.

2nd only option a and b because purchasing product from multiple different vendors does not helps in achieving improved security.

5th Oligomorphic are easier to detect compare to other two, Metamorphic changes its body every time so hard to detect

6th Typo-squatting depends on the user to make typos in typing the url and redirecting them to malicious website.

7th worms don't require any human assistance to transfer between systems they can use the network to transmitt.

virus and rootkits need the human assistance to transfer between system.
