OCI Application query - name change query

[yogi_2020]

Hi,

There is below question in OCI application.
"Have you ever changed your name? If yes, click the box and give details."

applicant last name is changed after marriage.

1) does above tick box to be selected as "Yes" ?
2) Or no selection required as name not changed and only last name is changed ??.

note: naturalisation certificate mentions full name as name after marriage. passport also have name after marriage.
also mentions name at birth which is with applicants before marriage last name.

Thanks
