Answer: Option A
Explanation:
One of the main reason for proposals is to propose a potential solution to a problem, or an analysis of a potential solution to a problem or a proposed plan of maintaining a system. It is actually meant to convince your clients or stakeholders about the success of such proposal.
So option A doesn't explain why we have proposals not to convince your clients that a problem exist, there won't be a proposal without a problem been identified ,it is not to justify the existence of a problem ,but we have proposals to prove a solution to a system.
At the beginning of the Revolutionary War, the British had set some goals. One goal was to blockade the colonial coastline. The British wanted to use their navy, which was a big strength for them militarily, to prevent supplies from entering and leaving the colonies. The British hoped that by cutting off the trade of the colonists that they would weaken the colonists and force them to surrender. John Paul Jones was involved in fighting...
The difference between the highest and lowest frequencies in a band or collection of frequencies is known as the bandwidth. The bandwidth in a standard North American telephone circuit is 64 Kbps. The amplitude or height of the wave is altered by amplitude modulation.

What do you mean by Telephone Circuits?</h3>
The standard line found in telephone circuits is this one. The frequency response of such a line resembles that of a low-pass RC filter. The telephone line loss and consequently the low-pass filter action increase in frequency as a result of the wires' increasing resistance, which causes an increase in I2R wire losses. 14 The frequency response of a 1 km-long, twisted line is reduced by 9 dB at 1 MHz and keeps going down for higher frequencies, Let's suppose that a straightforward, 1 km-long transmission system is required. A pair of 1 km long twisted copper wires may transmit data with a loss of less than 9 dB.
