**Core Concept**
Elemental iron and folic acid content in paediatric iron-folic acid (IFA) tablets are crucial for preventing and treating iron deficiency anaemia in children. The INCH programme is a government initiative to provide essential micronutrients to children.

**Why the Correct Answer is Right**
The paediatric IFA tablet supplied under the INCH programme contains 15mg of elemental iron (in the form of ferrous fumarate or ferrous sulphate) and 100 micrograms of folic acid. This combination is essential for addressing iron deficiency and promoting erythropoiesis in children. Folic acid is vital for DNA synthesis and repair, while iron is necessary for the production of haemoglobin.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as it does not match the standard elemental iron content of paediatric IFA tablets. The correct amount is 15mg.
* **Option B:** This option is incorrect as it does not align with the recommended folic acid content for children. The correct amount is 100 micrograms.
* **Option C:** This option is incorrect as it does not provide the correct elemental iron and folic acid content of paediatric IFA tablets.

**Clinical Pearl / High-Yield Fact**
To remember the correct elemental iron and folic acid content of paediatric IFA tablets, use the mnemonic "Fifteen for Folate" which stands for 15mg elemental iron and 100 micrograms of folic acid.

**Correct Answer: A. 15mg elemental iron and 100 micrograms of folic acid.**
