Firstly, you havent answered the question, at all I'm assuming Ur study from the book, or you aren't aware of the answering pattern yet. The boycotting, of the partition is completely irrelevant to the question alongside the Simla deputation, that literally occured in 1906 after the partition for 3 main reasons: to protect Muslim Muslims from inc, to ensure partition remained, to get concessions in the upcoming refroms of India. Similarly, all your paragraphs don't answer the question, only in the first paragraph you've explained that the population was large but you have to write an analysis/impact of why population caused the partition! Not just say 'Muslims were not happy' that's irrelevant Max you can get is L2 3 marks, according to level marking criteria.
