The present perfect tense usually follows the construction: 

Option B is the right answer. The construction implies that the action took place or began in the past and has continued into the present. The use of "has" or "have" depends on the verb's person. An English verb tense called the present perfect is used to describe previous activities that are connected to or continue in the present. The auxiliary verbs have and had, sometimes known as "helper verbs," make it simple to spot, as in "I have gone fishing ever since I was a child". Because there isn't always a direct translation in other languages, the present perfect is one of the most difficult verb tenses in English.

Because the structure is of present perfect continuous, Option A is erroneous.

Option C is erroneous since the construction is in the present simple tense.

Option D is erroneous since option B is correct.
