- A$(i)$ Increases continuously; $(ii)$ Decreases continuously
- B$(i)$ Decreases continuously; $(ii)$ Increases continuously
- C$(i)$ Increases continuously; $(ii)$ Decreases up to the group $IV$ and then increases up to the end of the period.
- D$(i)$ Decreases continuously; $(ii)$ Decreases up to the group $IV$ and then increases up to the end of the period.
