Concept:
Different glands and organs in the human body perform specialized physiological functions.
• Thymus plays a role in immunity and white blood cell development.
• Adrenal glands produce hormones responsible for the “fight or flight” response.
• Pancreas secretes digestive enzymes.
• Ovaries produce female sex hormones such as estrogen and progesterone.
Step 1: Match each organ with its function.
\[
\begin{aligned}
\text{Thymus} &\rightarrow \text{Make white blood cells}
\text{Adrenals} &\rightarrow \text{Fight or Flight}
\text{Pancreas} &\rightarrow \text{Digestive enzymes}
\text{Ovaries} &\rightarrow \text{Make Estrogen \& Progesterone}
\end{aligned}
\]
Step 2: Write the correct matching sequence.
Thus, the correct matching is:
\[
A-IV,\ B-I,\ C-II,\ D-III
\]
Hence, the correct answer is:
\[
\boxed{(D)\ A\text{-}IV,\ B\text{-}I,\ C\text{-}II,\ D\text{-}III}
\]
