Given below are two statements.

Statement I : Kidney failure may lead to decrease in the production of RBCs.

Statement II : Kidneys produce a hormone called erythropoietin. 

In light of the above statements, choose the correct answer from the options given below.

Erythropoietin secreted by kidneys help in the production of RBCs.

Statement I is correct because kidney failure can indeed lead to a decrease in the production of red blood cells (RBCs) due to the kidneys' role in producing erythropoietin, a hormone that stimulates the production of RBCs in the bone marrow.

Statement II is also correct because the kidneys produce erythropoietin, which plays a crucial role in regulating red blood cell production.
