D Correct answer
Explanation

Day 1: read 120 pages (240/2), 120 left. Day 2: read 60 pages (120/2), 60 left. Day 3: read 30 pages, 30 left. Each day you read half of what remains, so you always have half left. You'll approach completion but never actually reach it - it's an infinite series: 240 + 120 + 60 + 30 + ... = 480 pages total.
