right answer is- 'addressing'

shall and will use in future tense examples- shall- I and we will- she, he, it, they, you, name sometimes will use with ' I and we' and sometimes shall use with 'she, he, it, they, you, name'

has use in singular noun have use in plural noun example of has- it, she, he, name example of have- we, they, you, I

tum kese ho?- How are you? tum kya kar rahi ho?- what are you doing?
