Explanation of a past yr multiple choice question

The A Level H2 Biology worked solutions (2002-2010) for Paper 1 are out in Popular Bookshops. We advise you go through every past yr MCQ as questions may be repeated! By the way, the 2002-2010 worked solutions and the 2002-2011 Topical Series questions will be out early next year.

Those who bought the book will encounter a particular question that says "No answer (VOID)". This is because I find the question ambiguous - I have to assume that the molecule does not have anymore EcoR1 or Tac1 elsewhere other than the given section. So total no. of fragments is 5.

If I make the assumption, then the answer is C.
