Explanation:

Finance minister recently announced the Central Government’s plan to launch a mission to eliminate sickle cell anemia by 2047.

About Sickle cell anemia

• It is an inherited blood disorder.

• It affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. 

• People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.

• These sickle cells also become rigid and sticky, which can slow or block blood flow.

What causes it?

• The cause of Sickle cell disease is a defective gene, called a sickle cell gene.

• A person will be born with sickle cell disease only if two genes are inherited—one from the mother and one from the father.

Treatments

• The only cure for this disease is bone marrow or stem cell transplantation.

• However, there are treatments that can help relieve symptoms, lessen complications, and prolong life.

Hence only statement 2nd is correct.
