Answer:
The SBU best category that best describes the telecommunication unit is: d) Dogs.
Step-by-step explanation:
To understand this answer we need to remember the categories of SBUs.
First of all, we have stars: stars are companies with high growth in high share quadrants of a market. They require a big investment and they will become heavy revenue creators.
Second, we have cash cows, this category suits perfect companies with high growth in slow-growth markets. They generate more money than they need and invest in stars to diversify their business.
Third, Question marks are slow-growth companies in high growth markets. They very often require investment from cash cows. But as they are not very good they might represent a risky investment.
Fourth, dogs. This category suits slow-growth companies with low market share. They could generate enough cash to be a sustainable business however they don't represent a good business investment, thus the money is always moved to a better investment.
