A furniture retailer's app lets customers point their phone camera at their living room to see how a sofa would look in that space before buying. This is an application of:

Correct Answer: A) Augmented Reality (AR) — overlaying digital content onto the real-world environment in real time  —  the app overlays a digital object (the sofa) onto a live, real-world camera view in real time — exactly what defines Augmented Reality. Why the other options are excluded: • B refers to the merging of media formats/platforms generally, not specifically to overlaying digital objects onto a live camera view. • C concerns how content is ranked/distributed on social platforms, unrelated to this visualisation tool. • D concerns targeting specific audience segments with tailored messages, not a product-visualisation feature. Example (Pension Sector): An AR-based 'retirement corpus visualiser,' letting an NPS subscriber see a projected corpus grow on-screen under different contribution scenarios, would be a comparable pension-sector application of AR.
