Question

Match LIST-I with LIST-II
\begin{tabularx}{0.8\textwidth}{|l|X|l|X|} \hline \multicolumn{2}{|c|}{LIST-I} & \multicolumn{2}{c|}{LIST-II}
\multicolumn{2}{|c|}{Types Cancer} & \multicolumn{2}{c|}{Tissues involved}
\hline A. & Carcinoma & I. & Muscle
B. & Chondroma & II. & Cartilage
C. & Sarcoma & III. & Blood
D. & Myeloma & IV. & Epithelial Tissue
\hline \end{tabularx}
Choose the most appropriate answer from the options given below:

• A. A - IV, B - II, C - I, D - III
• B. A - III, B - II, C - I, D - IV
• C. A - II, B - I, C - IV, D - III
• D. A - I, B - II, C - IV, D - III

Hint:

Memorizing common medical prefixes is key for biology exams.

\textbf{Carcino-} = Cancer (from epithelial cells)
\textbf{Sarco-} = Flesh (connective/mesenchymal tissue)
\textbf{Chondro-} = Cartilage
\textbf{Myelo-} = Marrow/Spinal cord
\textbf{Hema-} = Blood \end{itemize} These prefixes can help you quickly deduce the origin of many cancer types.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This question requires knowledge of cancer terminology, specifically the classification of tumors based on their tissue of origin. The suffix "-oma" generally refers to a tumor, and the prefix indicates the tissue type.

Step 2: Detailed Explanation:
Let's match each cancer type in LIST-I with its corresponding tissue in LIST-II.
- A. Carcinoma: Carcinomas are malignant tumors that arise from epithelial cells. Epithelial tissues line the surfaces of organs and cavities throughout the body. Therefore, Carcinoma matches with Epithelial Tissue. (A \(\rightarrow\) IV).
- B. Chondroma: The prefix "chondro-" refers to cartilage. A chondroma is a benign tumor composed of mature cartilage. Therefore, Chondroma matches with Cartilage. (B \(\rightarrow\) II).
- C. Sarcoma: Sarcomas are malignant tumors that arise from mesenchymal tissues, which include connective tissues like bone, fat, and muscle. Therefore, Sarcoma matches with Muscle. (C \(\rightarrow\) I).
- D. Myeloma: The prefix "myelo-" refers to bone marrow. Myeloma (specifically multiple myeloma) is a cancer of plasma cells, which are a type of white blood cell produced in the bone marrow. Therefore, Myeloma matches with Blood (as it's a cancer of blood cells). (D \(\rightarrow\) III).

Step 3: Final Answer:
The correct pairings are: A-IV, B-II, C-I, D-III. This corresponds to option (A).
