Correct option is A
Explanation-
A. Leukemia → (ii) Hematopoietic cell cancer that does not grow as a solid tumor
Leukemia is a cancer of blood-forming (hematopoietic) tissues, especially the bone marrow and lymphatic system. It is non-solid (unlike tumors) and affects white blood cells.
So, A matches (ii).
B. Sarcoma → (iii) A tumor that develops from mesodermal connective tissue
Sarcomas arise from connective tissues such as bone, cartilage, fat, muscle, and blood vessels. These tissues originate from the mesoderm (embryonic layer).
So, B matches (iii).
C. Carcinoma → (i) A tumor that has arisen from endodermal tissue
Carcinomas originate from epithelial tissues, which include glandular and lining tissues of internal organs. Most epithelial tissues are derived from the endoderm (and sometimes ectoderm).
So, C matches (i).
D. Melanoma → (iv) Cancer that develops from the pigment-producing cells of skin
Melanoma arises from melanocytes, the pigment-producing cells found in the skin. This is a highly aggressive form of skin cancer.
So, D matches (iv).
Final Matching - A - ii , B - iii , C - i , D - iv
Correct Option - Option a
A-(ii), B-(iii), C-(i), D-(iv)
