The incidence of different malignancies varies with age. The correct matching of the age groups in List I with some of the commonly associated malignancies in List II is as follows:
\begin{itemize}
\item < 10 years (A): Eosinophilic granuloma (II) is a Langerhans cell histiocytosis that can affect various age groups, including young children.
\item Teenage (B): Ewing’s Sarcoma (III) is a primary bone cancer that is more common in teenagers and young adults.
\item Reproductive age (C): Breast cancer (IV) is a significant malignancy in women of reproductive age, although its incidence increases with age.
\item > 60 years (D): Multiple Myeloma (I) is a cancer of plasma cells that typically affects older adults, with the median age at diagnosis being in the 60s.
\end{itemize}
Therefore, the correct combination is (A)-(II), (B)-(III), (C)-(IV), (D)-(I).
