Match List-I with List-II:

List-I (Software Process Models)	List-II (Software Systems)
(a) Waterfall model	(i) e-business software that starts with only the basic functionalities and then moves on to advanced features
(b) Incremental development	(ii) An inventory control system for a supermarket to be developed within three months
(c) Prototyping	(iii) A virtual reality system for simulating vehicle navigation in a highway
(d) RAD	(iv) Automate the manual system for student record maintenance in a school

Choose the correct option from those given below:

Waterfall model is suitable when requirements are clear and well understood. Automating a manual student record maintenance system is a clear and structured requirement.

So,

$(a) \rightarrow (iv)$

Incremental development is used when basic functionality is developed first and advanced features are added later.

So,

$(b) \rightarrow (i)$

Prototyping is useful when the system is complex and requirements need to be understood through a working model. A virtual reality simulation system is suitable for prototyping.

So,

$(c) \rightarrow (iii)$

RAD means Rapid Application Development. It is suitable when software needs to be developed quickly within a short time.

So,

$(d) \rightarrow (ii)$

Therefore, the correct matching is

$(a)-(iv);\ (b)-(i);\ (c)-(iii);\ (d)-(ii)$
