Answer: d. No need to write N/A or not applicable" if it does not apply to you.
Step-by-step explanation:
Writing N/A or ''not applicable" when a part of the form does not apply to you is something that should be done when filling forms. It proves that the reader actually read the form and confirmed that the information required did not apply to them.
This is quite important because it would save the administrators from expending time and effort to find out if the information was omitted instead of being N/A. It can also work against the person filling the form if the administrators go ahead and decide that the space left unmarked even though not applicable, was omitted.
