Let

f(x)=\operatorname{sgn}(\operatorname{sgn}(\operatorname{sgn} x))

. Then

\lim \limits_{{x \rightarrow 0}} f(x)

View answer and explanation

Correct option: D

None of these

Option D (None of these) is correct because the left-hand limit and right-hand limit are not equal, so the limit does not exist.
