The correct answer is B.

OBJ-5.2: Cable certifiers can provide a “pass” or “fail” status following the industry standards and can also show detailed information such as “open,” “short,” or the length of the cable. When a short is detected, but the cable’s full length is shown (3 ft), this indicates the cable was incorrectly crimped. In this case, it appears that pin 3 and pin 6 are both crimped into the same position in the RJ-45 connector, causing the short. An open indicates that the electrical signal is not reaching the other end of the cable. A short indicates that the electrical signal is crossing two wires at the same time. Both of these are indications of a incorrectly crimped cable.
