​

Answer 1

Answer:

option A

the dog has been barking since morning.

Answer 2

The right option that fits in the blank is an option a: has been barking.

• This sentence says that any activity that is started is still going on which is a dog barking right from the morning and is still barking.
• This type of sentence uses the present perfect continuous form to write the correct structure of the sentence.
• The syntax is: Subject + has been/ have been + verb (ing form) + object.
• Option a is correct because according to the rule has been barking fits the sentence as the noun "dog" is a singular noun.
• Option b is incorrect because it is used with plural nouns.
• Option c is incorrect because it is the verb form of the past tense form.
• Hence, right option is option a.
