E Correct answer
Explanation

Statement II gives area of window = half of floor area = (1/2) × 35 = 17.5 sq m. But we don't know how many windows total or their individual areas. Statement I gives cost per sq m but without total area to paint, this is useless. Even together, we're missing: door area, exact window configuration, and we don't know if painting excludes door/window openings. The information is fundamentally incomplete. Option E is correct.
