The light duty anchor that is designed for easy installation and requires the head to be cut off for removal is indeed the nail-in anchor. This type of anchor is typically used in light applications where quick and straightforward anchoring is needed. The installation process involves simply hammering the anchor into the wall or base material. However, when it comes time to remove it, the distinctive feature of the nail-in anchor is that because it doesn't have a head protruding to allow for easy extraction, the only method is to cut off the head. This characteristic sets it apart from other anchors.

Lag bolts, machine screws, and toggle bolts have different designs and purposes. Lag bolts and machine screws are typically used in heavier applications and do not require cutting for removal. Toggle bolts serve a specific function for hollow walls and do not share the same characteristics as the nail-in anchor. The nail-in anchor’s construction and method of removal make it the right choice for this question.
