comment Banach Indicatrix Function
I wonder if it is necessary in a) that $f$ is continuous? I think one could assume that $f$ is a measurable function and an image $f([\alpha, \beta])$ is measurable for any interval $[\alpha, \beta]$.

comment There exist a sequence $Z_n$ with $Z_n \to Z_0$ such that $\lim_{n \to \infty} |f(z)| = \infty$
If $Z_0$ is pole then $\lim\limits_{z\to Z_0}f(z) = \infty$. If $\lim\limits_{z\to Z_0}f(z) = \infty$ then $\lim\limits_{n\to\infty}f(Z_n) = \infty$ for any sequence $Z_n\to Z_0$.
