Answer 1

a, c, d

Explanation:

1. Macroeconomics is the study of aggregates such as national GDP and total employment.
2. It addresses the interrelationship of several economic factors, such as inflation, unemployment, and national output.
3. Macroeconomics is a policy-oriented field that studies government policies aimed at promoting economic stability, growth, and employment. 

"It is based on certain assumptions," is not a defining feature of macro-economics itself, but more of a general characteristic of economic theories in general. Therefore, it's not included in the correct answer.
