which of the following?

Electromagnetic interference (EMI) would have no impact on which of the following?

A.
Fiber optics

B.
Category 5 twisted pair

C.
Broadband

D.
Category 3 twisted pair

Explanation:
Fiber optics have a sturdy glass or plastic casing that makes them
immune to EMI. EMI can result in transmission faults, especially if the cabling is
under heavy loads. Although the other choices all have different degrees of EMI
vulnerability, fiber optics would be the most resistant to this type of threat.
