ANSWER:

The correct options are: B- "Full employment is a macroeconomic goal" and D- "Inflation is the rise in the prices of goods and services".

EXPLANATION:

Macroeconomics studies issues like employment, inflation, poverty, unemployment etc. and so the goals of macroeconomics deal with all such issues.

"Full employment" refers to a 'situation' wherein every individual who has the capability to work and earn is provided with a job. Inflation is the "rise of prices" of services and goods .

Inflation makes it impossible for most people to buy even the necessary goods and services. Inflation also affects the demand of "goods and services".
