Step 1: Understand what is being asked.
This is a matching question. We need to match four types of plans (a, b, c, d) with their correct definitions (i, ii, iii, iv). Based on the solution provided, the four types are Policy, Programme, Method, and Strategy, matched to definitions about guiding thinking, detailed project statements, standard procedures, and comprehensive environmental plans.
Step 2: Match item (a): Policy.
A Policy is a general statement that provides a guide to thinking or channelises decision-making energy of managers in a specific direction. It sets boundaries within which decisions can be made. This matches definition (iv).
Step 3: Match item (b): Programme.
A Programme is a detailed statement about a specific project outlining the objectives, policies, procedures, rules, tasks, human and physical resources required, and the budget needed to implement a given course of action. This matches definition (ii).
Step 4: Match item (c): Method.
A Method is a prescribed way or manner in which a particular task has to be performed. It lays down the systematic and standard procedure for doing a specific activity. This matches definition (i).
Step 5: Match item (d): Strategy.
A Strategy is a comprehensive plan for accomplishing an organisation's objectives, taking into account the external business environment (competitors, government policies, market trends). It involves proactive actions to respond to environmental challenges. This matches definition (iii).
Step 6: Identify the correct combination and conclude.
The correct matching is: a-(iv), b-(ii), c-(i), d-(iii), which corresponds to option (B).
\[ \boxed{ \text{(B) a-(iv), b-(ii), c-(i), d-(iii)} } \]
