Why inductor is avoided in Integrated Circuit component?

(a) They provide many losses compared to other IC components

(b) IC devices are essentially two dimensions

(c) Device density of IC increases

(d) Fabrication process of these components are complicated

The question was posed to me in an interview.

My question is based upon Active and Passive Components of IC in division IC Fabrication of Linear Integrated Circuits

The accurate choice is (b) IC devices are essentially two dimensions

To put it plainly: Usually, IC devices are very small (~1 to 10µm). Even if IC inductor is made in form of a flat metallic thin film spirals. Very small value of the order nanohenry with low quality factor can only be obtained.
