Consider a message signal whose spectrum is given by $$M\left( f \right) = 1 - \frac{{\left| f \right|}}{{{{10}^4}}},\,\left| f \right| \leqslant {10^4}$$ and zero elsewhere. The message signal amplitude modulates a carrier fc = 1 MHz. The bandwidth of the modulated signal is:
A. 20 KHz
B. 1.01 MHz
C. 1.02 MHz
D. 10 KHz
