Break Down the Problem

1. Identify the keywords provided in the options.
2. Understand the context of class inheritance in programming.

Relevant Concepts

1. In many programming languages, particularly Java, C#, and others, specific keywords are used for inheritance.
2. "extends" is commonly used to indicate that a class is inheriting from a superclass.

Analysis and Detail

1. this: Refers to the current instance of the class. It is not used for inheritance.
2. super: Refers to the superclass of the current instance. It is used to access methods and constructors of the superclass but is not the keyword for declaring inheritance.
3. extend: This is not a keyword used in class inheritance. The correct form is "extends".
4. extends: This keyword is explicitly used to denote that a class is inheriting characteristics from another class.

Verify and Summarize

Based on the analysis, the correct keyword for class inheritance is "extends". The other options do not serve this purpose.

Final Answer

extends
