Not attemptedCorrect Answer: (b) 1, 3 and 4 only
Bio-asphalt is produced from renewable, plant- or waste-based feed-stocks, so it is not based on fossil fuels (statement 1) and can be made from organic waste materials (statement 3). Its renewable origin and lower life-cycle emissions make it eco-friendly for road surfacing (statement 4). However, it is specifically valued because it avoids non-renewable resources, so statement 2 is incorrect. Therefore only 1, 3 and 4 are correct → option (b).
