    Option A: 500 pages

    Explanation:

    1. Number of pages of the first 5 novels

    Average = [Number of pages] / [number of novels]

    450 pages / novel = Number of pages / 5 novels

    Number of pages = 5 novels * 450 pages / novel = 2,250 pages

    2. Average length of all 6 novels

    Average = [Number of pages] / [number of novels]

    Number of pages of 6 novels = 2,250 pages + 750 pages = 3,000 pages

    Average = 3,000 pages / 6 novels = 500 pages / novel
