A data analyst is working with a data frame named weather. It has separate columns for temperatures $($temp$)$ and measurement units $($unit$).$ The analyst wants to combine the two columns into a single column called display$\_$temp, with the temperature and unit separated by the string $$ Degrees $.$ What code chunk lets the analyst create the display$\_$temp column?

$1$ point

weather $\%>\%$ unite$($weather$,$ "display$\_$temp", weather, temp, delim $="$ Degrees $")$

weather $\%>\%$ unite$("$ Degrees $",$ weather, temp, "display$\_$temp"$)$

unite$($weather$,$ "display$\_$temp", temp, unit, sep $="$ Degrees $")$

unite$("$ Degrees $",$ weather, temp, "display$\_$temp"$)$
