Q. In a resource allocation scenario, if a company decides to allocate more funds to marketing rather than research and development, this is an example of: (2023)
A.
Budget reallocation.
B.
Resource optimization.
C.
Opportunity cost.
D.
Strategic planning.
Solution
This decision reflects budget reallocation, as funds are being shifted from one area to another, making option 0 correct.
Q. In a resource allocation scenario, which of the following factors is least likely to influence decision-making?
A.
Cost-benefit analysis.
B.
Stakeholder interests.
C.
Personal biases of decision-makers.
D.
