Answer:
The present perfect tense refers to an action or state that occurred at an indefinite time in the past or began in the past and continued to the present time. This tense is formed by have/has + past participle. You can use the present perfect to talk about the duration of something that started in the past is still happening. Here, the state of not eating since morning has continued to the present. Hence, Option B is correct.
The rest of the options do not express this condition. They mention continuous actions without an auxiliary/helping verb (option A), actions that are yet to happen (option C) or incorrect verb forms 'have + have' (option D). 'Have + have' is not the desired verb form, because the latter 'have' must be conjugated, and 'have' as a main verb (latter) is a base verb.
Hence these options are incorrect.
