Answer:
II Clara is using competitive parity budgeting methods
IV Clara is using objective and task budgeting
Step-by-step explanation:
Share of voice basically measures your brand's share of total advertising in a market. It is very useful to determine your brand's visibility and helps to develop you company's external competitive analysis. It differs from market share since market share represents the actual share of total market sales that your company has.
In this case, Clara is adjusting her marketing budget to reach the appropriate share of voice for Wizard air freshener. She needs to compare the product's current share of voice with the competition's and the projected marketing expenses for next year.
A high share of voice doesn't necessarily match a high market share, although it helps to increase it.
