4. a – iv – b – iii, c – I, d - ii

Answer 1

Correct Answer - Option 1 : a – ii, b –i, c – iv, d - iii

It is as per IEEE (institute of electrical & electronics engineering) standards that the frequency bands are divided.

Different kinds of satellites use different frequencies.

The table below explains the different frequency bands along with their applications:

Band	Frequency Range	Total Bandwidth	General Application
L	1 to 2 GHz	1 GHz	Mobile satellite service (MSS)
S	2 to 4 GHz	2 GHz	MSS, NASA, deep space research
C	4 to 8 GHz	4 GHz	Fixed Satellite Service (FSS)
X	8 to 12.5 GHz	4 .5 GHz	Terrestrial earth exploration, meteorological satellites
Ku	12.5 to 18 GHz	5.5 GHz	Broadcast satellite service (BSS)
K	18 to 26.5 GHz	8.5 GHz	BSS, FSS
Ka	26.5 to 40 GHz	13.5 GHz	FSS
