British citizenship for ILR obtained via Tier-1 Ent 3 year route

[forafriendinneed]

Hi All,
My friend has obtained ILR in feb 2019, and the confusion is whether he is eligible for naturalisation in feb 2020.
1) The confusion is because ILR was obtained through 3 year route of Tier-1 ENT and he is in the UK via Tier-2 general since 2014 (continuous stay is more than 5 years).
Question is whether he is eligible for naturalisation and does he satisfy 5 year stay in the category?
2) And it is not clear whether he has to fill 3 year category or 5 year category while completing the
application form.
3) Also Is there any extra details required in this application category.

Thanks
FAFIN

The rule is resident in the UK for 5 years (subject to allowable absences) unless your are the spouse/civil partner of a British citizen. It is not about the type of stay. Purely 5 years legal residence.

Additionally, must have ILR for 12 months and have been physically present in the UK exactly 5 years prior to the day in which you submit the online application AN.

Thank you very much for the clarification.
