Which of the following is true about Ionosphere?

A Its density is lesser at short distances from planetary surface in morning and further decreases as ionosphere rises at night-time, thereby allowing a greater range of radio frequencies to travel greater distances
B Its density is greater at short distances from tplanetary surface in daytime and decreases as ionosphere rises at night-time, thereby allowing a greater range of radio frequencies to travel greater distances
C Its density is greater at long distances from planetary surface in daytime and further increases as ionosphere rises at night-time, thereby allowing a greater range of radio frequencies to travel greater distances
D None of the above
Correct Answer: Its density is greater at short distances from tplanetary surface in daytime and decreases as ionosphere rises at night-time, thereby allowing a greater range of radio frequencies to travel greater distances
