Solution

The correct option is A

2×105


The explanation for the correct answer is,

Step 1. Given Data:

Carrier frequency =10GHz=10×109Hz

Step 2. 10% is used in transmission:

10100×10×109Hz=1×109Hz

Step 3. As we know:

Each channel requires, 5×103Hz

No of channels, n = (carrier frequencyx0.1) / channel bandwidth

n=(0.1x10x109)(5x103)n=2x105

Hence, the correct option is (A).
