James ... a car in front of the sports shops.

The question is about choosing the correct form of the verb "stop" to complete the sentence. The sentence describes a past action. Let's analyze the options:

• didn't stoped: This is grammatically incorrect. The auxiliary verb "did" is used with the base form of the verb, so it should be "didn't stop".
• stopped: This is the correct past tense form of the verb "stop" and fits grammatically and contextually to describe a past event.
• stoped: This is a misspelling of the past tense of "stop". The correct past tense is "stopped".
• didn't stopped: This is grammatically incorrect. After "didn't", the base form of the verb "stop" should be used, not the past tense "stopped".

Therefore, the most appropriate and grammatically correct option to complete the sentence is "stopped".
