The correct option is A a-3,b-5,c-4,d-2,e-1

• A neoplasm is a type of abnormal and excessive growth, called neoplasia, of tissue. Neoplasms are classified into four categories - benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behaviour.
  
• A benign tumour is a mass of cells (tumour) that lacks the ability to invade neighbouring tissue or metastasize. Benign tumours are noncancerous growths in the body. Unlike cancerous tumours, they don't spread (metastasize) to other parts of the body. Benign tumours can form anywhere.
• Carcinoma is a type of cancer that starts in epithelial cells that make up the skin or the tissue lining organs, such as the liver or kidneys. Like other types of cancer, carcinomas are abnormal cells that divide without control.
  
• Sarcoma is a malignant tumour of connective or other non-epithelial tissue. , Malignant tumours made of cancellous bone, cartilage, fat, muscle, vascular tissues are considered sarcomas.
  
• A lymphoma is a group of blood cancers that develop from lymphocytes (a type of white blood cell). Thus, lymphomas and leukaemias are both tumours of the hematopoietic and lymphoid tissues.
  

So, the correct answer is 'A'.
