 A.  is wrong because (could'nt) is not the proper way to write the contraction for 'could not' it should be 'couldn't', also there is no need for the apostrophe after the word, yours it already possessive without the apostrophe.
B.  is wrong because 'couldnt' is not the correct way to write the contraction for 'could not', it's couldn't.
C. She couldn't remember which suitcase was your's. is wrong because you don't need the apostrophe in your's because it possessive is, yours. 
The sentence that contains no errors is D. She couldn't remember which suitcase was yours.
Hope this helps. :)

We can actually see here the sentence below changes mood. Therefore it is a YES.
<h3>What is mood?</h3>
In grammar, grammatical mood actually talks about the form of a verb as seen in a sentence. It usually denotes the tone of a verb used in a sentence which clearly states what the writer or speaker is saying.
There are three main verb moods. They are:
- Indicative mood
- Imperative mood
- Subjunctive mood.
We see here that mood isn't "feelings" but rather a form of verb that is written or spoken with an intention.
Thus, we see here that the given changes mood. This is true because there is a "take stock" and then a "stop".
