Explanation

The data is 42GB, so the media must hold at least that amount. Blu-Ray single-layer holds approximately 25GB - insufficient. HD-DVD holds up to 15GB (single-layer) or 30GB (dual-layer) - insufficient. DVD-18 is a dual-layer, dual-sided DVD with a capacity of approximately 17-18GB - insufficient. Blu-Ray dual-layer (BD-DL) holds approximately 50GB, making it the only option listed that can accommodate 42GB of data. This is the correct choice for transporting large forensic disk images on removable optical media.
