Concept:
Cancer is an uncontrolled proliferation of cells. Depending upon the tissue of origin, cancers are classified into different categories such as carcinoma, sarcoma, leukemia, and lymphoma.
Step 1: Examining Carcinoma.
Carcinoma originates from epithelial tissues such as skin, lining of organs, and glandular tissues.
Therefore,
\[
\text{Carcinoma} \rightarrow \text{Epithelial tissue}
\]
is correctly matched.
Step 2: Examining Sarcoma.
Sarcoma develops from connective tissues such as bone, cartilage, muscle, and adipose tissue.
Therefore,
\[
\text{Sarcoma} \rightarrow \text{Connective tissue}
\]
is correctly matched.
Step 3: Examining Leukemia.
Leukemia is commonly known as blood cancer because it affects blood-forming tissues and white blood cells.
Thus,
\[
\text{Leukemia} \rightarrow \text{Blood}
\]
is correctly matched.
Step 4: Examining Lymphoma.
Lymphoma is a cancer of the lymphatic system and lymphocytes.
It does not originate in nervous tissue.
Hence,
\[
\text{Lymphoma} \rightarrow \text{Nervous tissue}
\]
is an incorrect match.
Therefore, the mismatched pair is Option (D).
