When applying for a National Insurance number, the primary requirement is to provide documents that prove your identity and your permission to work in the UK. This is essential because the National Insurance number is linked to your ability to work and contribute to the social security system.

Proving identity is crucial as it verifies that you are who you say you are, which helps to prevent fraud and ensures that the system is secure. Additionally, having documents that indicate permission to work demonstrates that you are legally allowed to earn money in the UK, which is a fundamental aspect of the National Insurance system.

The other options, while they encompass important aspects of an individual's life (like financial status or education), do not specifically relate to the requirements for obtaining a National Insurance number. Hence, those would not be the correct types of documents needed for this particular application process.
