Show Answer
The players were practicing for an hour
Here, the erroneous part is "The players were practicing for an hour."

Key Points
- In the corrected version, "had been practicing" must be used to indicate the continuous action that started before a certain point in the past (an hour ago) and continued up to that point when the coach arrived.
- The past perfect continuous tense is used to indicate a continuous action that started in the past, continued up to a certain point in the past, and may or may not have continued after that point.
- It is formed using "had been" + the present participle (verb + ing).
- "For" is used to indicate the duration of the action.
- Example: She had been studying for three hours before she finally took a break.
- The correct answer is Option 1.
Correct sentence: The players had been practicing for an hour when the coach came and asked them to stop.
