What elements are included in the frequency spectrum of an AM signal produced by a sinusoidal modulating signal?

Correct option is B

​$$\text{For \textbf{Amplitude Modulation (AM)} with a \textit{sinusoidal modulating signal}, the transmitted spectrum contains:} \\[6pt]\bullet \ \textbf{Carrier frequency } f_c \\[2pt]\bullet \ \textbf{Upper sideband (USB)} \text{ at } f_c + f_m \\[2pt]\bullet \ \textbf{Lower sideband (LSB)} \text{ at } f_c - f_m \\[6pt]\text{Noise is not part of the generated AM signal; it may appear during transmission but is not an inherent component.}$$​​
