The table shows the incidence rate and mortality rate for two types of cancer \((X, Y)\) with the highest mortality rate for females in Australia in 2017.
\begin{array} {|c|c|c|}
\hline
\rule{0pt}{2.5ex}\textit{Type of cancer}\rule[-1ex]{0pt}{0pt} & \textit{Incidence rate} & \textit{Mortality rate} \\ & \textit{per 100 000} & \textit{per 100 000}\\
\hline
\rule{0pt}{2.5ex} X \rule[-1ex]{0pt}{0pt} & 36.2 & 21.8 \\
\hline
\rule{0pt}{2.5ex} Y \rule[-1ex]{0pt}{0pt} & 124.8 & 19.2 \\
\hline
\end{array}
Which statement best explains why cancer Y has a lower mortality rate than cancer X ?
- Government funding has increased for research into treatment options for cancer Y.
- Health services have been reoriented so that cancer Y is detected and treated earlier.
- Individuals have enhanced their personal skills to effectively address the modifiable risk factors for cancer Y.
- An increased number of out-patient health services for cancer Y has improved access for the priority population group.
