A$1)$ Classify the following different types of active galaxies $($AGN$)$ based on their characteristics: $($i$)$ A highly luminous nucleus $($Lbol $>1038\mathrm{.}5$ W$,$ with Lbol the bolometric luminosity$)$ with both broad and narrow emission lines and very little radio emission. $($ii$)$ A moderately luminous nucleus $($Lbol $>1034\mathrm{.}5$ W$)$ with narrow emission lines and very little radio emission. $($iii$)$ A moderately luminous nucleus $($Lbol $>1035\mathrm{.}5$ W$)$ with both broad and narrow emission lines and very little radio emission. $($iv$)$ A lower luminosity nucleus $($Lbol $>1033\mathrm{.}5$ W$)$ with weak emission lines but moderate radio emission. $($v$)$ A luminous radio source $($bright nucleus but also extended radio emission$)$ with only narrow optical spectral lines. $($vi$)$ A luminous radio point$-$source with a highly polarised optical continuum with weak spectral lines.
