ii coaxial braid-breaker

1. i and ii are both true
2. i is true but ii is false
3. i is false but ii is true
4. i and ii are both false

The answer is :- 1A ferrite ring or coaxial braid-breaker are possible solutions to interference on a nearby television receiver. Some (particularly cheaper) televisions can be extremely susceptible to a stray r.f. signal, due to insufficient filtering components.
