RNA polymerase is active in Both G1 and G2 phase.
In G1 phase the first growth phase , since it involves synthesis of RNA, proteins and membranes which leads to the growth of nucleus and cytoplasm of each daughter cell towards their enhancing size.
In G2 phasesynthesis of RNA and proteins continues which is required for cell growth.
For synthesis of RNA, RNA polymerase is required for transcription.
So option should be 4)
