(c) Polycythemia
(d) Tac-sac disease

Answer 1

Hint: Folic acid is a kind of vitamin which is responsible for the production of white blood cells (WBCs). White blood cells are considered to be the soldiers of the body.

Complete solution:
White blood cells are considered to be the soldiers of our body. White blood cells fight against the antigens that invade in our body. Thus maintaining an average number of white blood cells is essential for maintaining Immunity. White blood cells are also known as Leukocytes. Folic acids are a certain class of vitamins which are responsible for the production of Leukocytes.
Leukaemia is a condition in which, white blood cells grow in an exponential amount. This is also referred to as cancer of blood-forming tissues, including bone marrow. Types of leukaemia are acute lymphoblastic leukaemia, acute myeloid leukaemia and chronic lymphocytic leukaemia.
Causes of leukaemia can be many, some of them are:-
A genetic predisposition, Down syndrome, Human T-lymphotropic virus (HTLV), Human immunodeficiency virus (HIV), Exposure to petrochemicals, such as benzene, Extensive exposure to artificial ionizing radiation. Treatment is highly variable as Alkylating chemotherapy agents are administered to treat other types of cancer. For slow-growing leukaemia conditions, treatment may include monitoring. For aggressive leukaemia conditions, treatment includes chemotherapy this is also followed by radiation and a stem-cell transplant.

So, the correct answer is ‘Leukopenia’.

Note:
Folic acid is also known as vitamin B9. Folate is responsible for the production of red blood cells and is found in certain foods. When a deficiency of folic acid is detected in a body thus, deficiency of Leukocytes is detected. This condition is known as Leukopenia.
