The Above sentence is going to present perfect tense
have/has + past participle.
you------> noun
Ever' and 'never' are always placed before the main verb (past participle). Ever is used: In questions
****
Option C is correct "as ever been "indicates the use of the present perfect tense. Also, have is used as an auxiliary here.
An auxiliary verb is used to form tenses, moods, tones, etc.
***
The other options are wrong as no other tense other than the present perfect tense can be used.
