Rectifying error:

• In the question given, we must find out the error in it and also correct it.
• When we are given a sentence to spot the mistake, we must check if there is agreement among the parts of speech in it.
• Especially, the agreement between subject and verb must be looked into.
• Further we have to see if the prepositions are properly used. Then we must also check if the tense is used correctly.
• In the given sentence the conjunction 'since' is followed by a clause that is in simple past. So the time after that must be in present perfect.
• But here the verb used is grammatically wrongly as 'is been'. It should be 'has been'.
• Therefore the answer is: It has been a long time since I had mango ice cream.
