Why monolithic IC transistor is preferred over discrete planar epitaxial transistor?

(a) Due to structural difference

(b) Increase in VCE (sat) and collector series resistor

(c) Improvement in circuit performance

(d) All of the mentioned

I had been asked this question during an online exam.

My question is from Active and Passive Components of IC topic in section IC Fabrication of Linear Integrated Circuits

The accurate answer is (d) All of the mentioned

Here's an easy explanation: As the collector contact is present on the top of IC transistor, it makes structural difference. Hence, it increases collector series resistance and VCE(sat) of device. From this, circuit performance is highly improved as matched transistor can be obtained.
