The circular flow of income refers to the continuous production of goods and services, income generation and consumption. It involves the movement of money from businesses to households in the form of wages and back to businesses in the form of consumer spending.

1. Higher Imports: Importing goods and services from other countries represents a leakage from the circular flow of income because it involves spending income on goods and services that are produced abroad. Therefore, higher imports would not increase the circular flow of income. So, the answer is NO.

2. Higher Investment: Investment is an injection into the circular flow of income. When businesses invest, they are putting money into the economy, which can then be used to pay wages and buy other goods and services. Therefore, higher investment would increase the circular flow of income. So, the answer is YES.

3. Higher Taxation: Taxes are a leakage from the circular flow of income. They represent money taken out of the economy by the government. Therefore, higher taxation would not increase the circular flow of income. So, the answer is NO.

So, the correct answer is D (No, Yes, No).
