The correct answer is: a) Small population size.
Sikkim is a small state with a population of just over 700,000 people. This means that there is a smaller pool of potential advertisers than in larger states, such as Maharashtra or Uttar Pradesh. Additionally, the state’s economy is relatively underdeveloped, which means that businesses may have less money to spend on advertising.
The other options are also possible factors that could contribute to limited advertising revenue for media outlets in Sikkim, but they are less likely to be the main cause. Option b, competition from online media, is a potential challenge for media outlets in all states, but it is likely to be less of an issue in Sikkim, where there is a lower penetration of internet access. Option c, government restrictions, is also a potential challenge for media outlets in all states, but it is unlikely to be a major factor in Sikkim, where the government has a relatively hands-off approach to the media. Option d, lack of consumer interest, is also a potential challenge for media outlets in all states, but it is likely to be less of an issue in Sikkim, where there is a strong demand for news and information.
In conclusion, the small population size of Sikkim is the most likely reason for limited advertising revenue for media outlets in the state.
