Answer 1

Right answer is (d) Unauthorized network access

For explanation I would say: The different vulnerabilities of the Transport layer are mishandling of undefined, poorly defined, Vulnerability that allow “fingerprinting” & other enumeration of host information, Overloading of transport-layer mechanisms etc. Unauthorized network access is an example of physical layer vulnerability.
