When modulation is increased the power of side bands increase.

Hence (b) is the correct option.

Answer 2

Sideband

If level of modulation is increased Sideband power is increased.

• As modulation level rises, so does noise and interference sensitivity. Later modifications called for enhanced FEC, which allowed for a greater code rate—the proportion of data bits to all other bits (including code bits) in a code block.
• the range of frequencies below the carrier frequency in which the spectral components created by carrier wave modulation fall.
• There are options for upper and lower sideband when utilising SSB to operate an amateur radio station. The usage of Lower Sideband, LSB, in frequencies below 10 MHz and Upper Sideband, USB, in frequencies above 10 MHz is commonly recognised.
• For frequency modulation (FM), the number of significant sidebands rises as the modulation index rises, while the sidebands' combined average power stays constant.
• Regardless of the audio frequency, overmodulation causes the waveform or envelope of the transmitted signal to have sharp edges or bends. The modulated carrier emits spurious signals as a result, and the recovered modulating signal is distorted.
