Change of name deed after Naturalization for British passport application for no surname in Indian passport

Hello all,
Looking for options on how to proceed with British passport application ( already naturalised)with following where surname blank in Indian passport:

Indian passport:
Surname-
Given name- Niki Namrata

Naturalisation certificate-Niki Namrata
I understand that surname is mandatory in British passport.So I am looking for options to have correct surname 'Namrata' in the British passport.

Option 1: Surrender indian passport and get the cut Indian passport and then apply for British passport.

Option 2: try for a change of name, adding surname in indian passport before applying for British passport.( have been naturalised already)

Option 2:Do a change of name deed stating Namrata as my surname and attach that with my British passport application?Any supporting docs for surname thing suggested?Do the surrender of Indian passport in between while British passport application is in process?

Option 3: Apply for British passport with as it is no surnmae in indian passport and then once British passport comes.If it does not come correct with SUrname, given name , then do a change of name deed fir correction?


Thanks all.
