In satellite communication
1. The frequenc used lies between 5 MHz and 10 MHz.
2. The uplink and downlink frequencies are different.
3. The orbit of geostationary satellite lies in the equatorial plane at an inclination of `0^(@)`.
In the above statements

Options

A. only 2 and 3 true
B. all are true
C. only 2 true
D. only 1 and 2 true

Explanation

In satellite communication, the frequency used is more than 40 MHz. The uplink and downlink frequencies are different to avoid distortion of signal and the orbit of geostationary satellite lies in the equatorial plane at an inclination of `0^(@)`.
