ESI show cause notice - How to reply to the department? and what are the required documents?

Sir/Madam,

I have received a show-cause notice for the late registration of an employee in ESI. However, I am unsure about the specific date mentioned as the date of joining during the registration process. How should I respond to the department, and what documents are required for this purpose?

Please provide me with guidance on how to address this issue.

Thank you.
