Objective is the point of view that is most like a video camera recording events.
In obejctive point of view, it contains no interpretation or access to the thoughts or feelings of others present. This POV only reports what is seen or heard, and allows the spectator to form their own opinions.
i want to buy <u>a</u> washing machine i like <u>the</u> one i saw on TV.
<em>i think those are it i mean there are no optional words???</em>

B. A possessive noun should have its instead of it's (which is a contraction for it is).
For A. Diana is a singular noun and the apostrophe should come after the r instead of after the s.
For C. The duck would've dunked ITS instead of IT'S beak since it is possessive.
For D. You do not need to put an apostrophe since theirs is already a possessive noun.
There is some info lacking here.
