Explanation:

In the context of crane or boom - related engineering (falling under the Engineering sub - field of Natural Science), the extension attached to the boom point that provides added boom length for lifting specified loads is called a "Jib". Among the given options, "Jib" is the correct term for this component. The other options: "Block" is used for lifting and rigging in a different way, "Boom stop" is for limiting boom movement, and "Hoist" is for lifting the load, not for extending the boom length.

Answer:

Jib (assuming the option with "Jib" is one of the choices; if the options are as partially visible, and "Jib" is an option, then the answer is the option with "Jib" text. Since the options are partially shown, but based on engineering knowledge, the correct component is Jib.)
