Christie measured the temperature every 3 hours from 6:00 am to 3:00 pm.
\begin{array} {|l|c|c|c|c|}
\hline
\rule{0pt}{2.5ex} \text{Time of the day} \rule[-1ex]{0pt}{0pt} & \text{6 a.m.} \rule[-1ex]{0pt}{0pt} & \text{9 a.m.} \rule[-1ex]{0pt}{0pt} & \text{12 p.m.} \rule[-1ex]{0pt}{0pt} & \text{3 p.m.} \\

\rule{0pt}{2.5ex} \text{Temperature (°C)} \rule[-1ex]{0pt}{0pt} & \text{22} \rule[-1ex]{0pt}{0pt} & \text{27} \rule[-1ex]{0pt}{0pt} & \text{32} \rule[-1ex]{0pt}{0pt} & \text{26} \\

\(\text{1st increase } = 27-22 = 5^{\circ}\)
\(\text{2nd increase } = 32-27 = 5^{\circ}\)
\(\longrightarrow\ \text{Temperature then drops 6° to 26°}\)
\(\Rightarrow B\)
