MCQ

This question has Statement $- 1$ and Statement$- 2$. Of the four choices given after the statements, choose the one that best describes the two statements.
Statement $- 1$ : Sky wave signals are used for long distance radio communication. These signals are in general, less stable than ground wave signals.
Statement $- 2$ : The state of ionosphere varies from hour to hour, day to day and season to season.

A
Statement$-1$ is true, Statement$-2$ is true, Statement$-2$ is the correct explanation of Statement$-1.$
✓
Statement$-1$ is true, Statement$-2$ is true, Statement$-2$ is not the correct explanation of Statement$-1.$
C
Statement$- 1$ is false, Statement$- 2$ is true.
D
Statement$- 1$ is true, Statement$- 2$ is false

✓

Answer

Correct option: B.

Statement$-1$ is true, Statement$-2$ is true, Statement$-2$ is not the correct explanation of Statement$-1.$

b
For long distance communication , sky wave signals are used.

Also, the state of ionosphere varies every time. so, both statement are correct.
