Final answer:
The error in the sentence is in the phrase 'to get married without her parents at her side.' It should be 'married without her parents by her side.'
Step-by-step explanation:
The question is asking to identify whether a grammatical error exists within a given sentence and, if so, to select the option that corrects it.
The error in the sentence is in option c) to get married without her parents at her side. The correct phrase should be 'married without her parents by her side.'
Here, 'by her side' means that her parents are not physically present with her during the marriage ceremony. The correct sentence would be: 'The entire room teared up when the bride said how difficult it was to get married without her parents by her side.' This change in preposition provides a clearer meaning to the sentence.
