Match the Agile Process models with the task performed during the model:

	List I		List II
a.	Scrum	i.	CRC cards
b.	Adaptive software development	ii.	Sprint backlog
c.	Extreme programming	iii.	<action> the <result> <by/for/of/to> a(n) <object>
d.	Feature driven development	iv.	Time box release plan

Choose the correct option from those given below:

1) Scrum model: It is an agile project management methodology which articulates a set of values and principles to guide decisions on how to develop high quality software. It is related with sprint backlog. Sprint backlog is a list of tasks identified by scrum team to be completed during scrum sprint.

2) Adaptive software development: It is a design principle for creation of software systems. It focuses on rapid creation and evolution of software. It is a series of three steps: speculate, collaborate and learn. It considers <action> the <result> <by/for/of/to> a(n) <object>.

3) Extreme programming: It is a methodology designed to improve the quality of software. It uses CRC modelling which includes CRC cards that divided into three sections: class name, responsibilities and collaborators.

4) Feature driven development: It is a client centric and pragmatic software process. Features are an important aspect of feature driven development. A feature is a small, client valued function expressed in the form. It is based on time box release plan as time boxing is used as project planning technique.
