Match List I with List II and select the correct answer from the codes given below :

List I	List II
(a) Decision tree	(1) Trial and error approach to complex problems
(b) Simulation	(2) Group decision technique
(c) Delphi Technique	(3) Graphic method to see alternative solutions
(d) Link-pin concept	(4) Avoid face to face communication

Codes : (a) (b) (c) (d)

Answer: A

The correct code is (3) (1) (4) (2).

(a) A decision tree is a graphic method that lays out the alternative courses of action and their outcomes as branches.
(b) Simulation is a trial and error approach to complex problems, testing alternatives on a model instead of in reality.
(c) The Delphi technique collects expert opinion through repeated anonymous questionnaires, so it avoids face to face communication.
(d) Rensis Likert's link-pin concept links overlapping work groups, each manager being a member of two groups, and is matched here with group decision making.

Only option A gives decision tree (3), simulation (1) and Delphi (4); every other code puts at least one of these three in the wrong place.
