• D. 1-b ,2-d ,3-a ,4-c

Answer 1

The correct option is D 1-b ,2-d ,3-a ,4-c

Answer is D.
The right matches are given below.
1. Mass - b. kilogramII. same everywhere
2. Weight - d. Newton IV. depends on the altitude
3. Gravitational acceleration - a. $m/s^2$I. zero at the center
4. Gravitational constant - c. $N{m}^{2}k{g}^{-2}$III. remain constant in the universe
