Master budget includes all projections of company’s budget and focuses on

serial correlation
marketing plan
financial plan
both B and C

The correct answer is: C. financial plan.

A master budget is a comprehensive financial plan for a company. It includes all projections of the company’s budget, such as sales, expenses, and profits. The master budget is used to guide the company’s operations and to make sure that it is on track to meet its financial goals.

A marketing plan is a document that outlines a company’s marketing strategy. It includes information on the company’s target market, its marketing objectives, and its marketing mix (product, price, place, and promotion). The marketing plan is used to guide the company’s marketing efforts and to ensure that it is reaching its target market effectively.

A serial correlation is a statistical measure of the correlation between two variables that are measured over time. It is used to determine whether there is a relationship between the two variables and to assess the strength of that relationship.

Neither serial correlation nor a marketing plan is included in a master budget.
