Complete answer:
In the given question, we have to find out which of the options includes the answer in the present perfect tense, as the tense from the question sets the tense here.
Let us thus analyze the options given to us in this question -
Option (a.), 'have just seen', refers to present perfect tense. Therefore, option (a.) is incorrect as ‘have’ is not used for first-person pronouns.
Option (b.), ‘had already seen', refers to past perfect tense. Therefore, option (b.) is incorrect as we need the answer in the present perfect tense.
Option (c.), ‘have not seen', refers to the negative form and present perfect tense. Therefore, option (c.) is incorrect as ‘yes’ indicates the usage of positive forms of words after it.
Option (d.), ‘has just seen', refers to present perfect tense. Therefore, option (d.) is correct as we need present perfect tense in here since the given sentence expresses an action completed in the present (seeing Julia).

Note:
In this question, it will be helpful for the student to recall the concept of tenses. Tense is a grammatical category of verbs used to express distinctions of time. There are three tenses - past, present, and future.
