Which of the following tools is generally used to grip and twist objects?

Pliers are specifically designed for gripping, twisting, bending, and even cutting objects. They consist of two handles that are connected to a pair of jaws, allowing the user to apply significant force to securely grasp various materials. This makes pliers highly versatile for tasks that require precision and strength, such as holding wires, assembling components, and manipulating small objects.

The other tools listed serve different purposes: a hammer is primarily used for driving nails or breaking apart objects; a socket wrench is designed for loosening or tightening fasteners, particularly nuts and bolts, with a rotating motion; and a tape measure is a length-measuring tool that does not grip or twist objects. The specific function of pliers as a gripping and twisting tool makes them the correct choice for this question.
