90% sure it's D. And I have to make this answer long or else I can't submit it so that's why I added this whole sentence
If the underlined word is only 'barking', then the correct answer is B) present participle, because those are used to form present progressive tense, as is the case here.
A) would be 'barked'.
C) would be 'bark/barks'.
D) would be 'barked', the same as A.
He he he just say in the end and write something random after
3. C instead of a ; you couldve just used a comma
4. D. You need an apostrophe after the B in Bs
7. C supposed to be melissa and I
adj
adv
hope this helps!
