(A) According to the Maxwell-Boltzmann distribution law,the $x$-axis represents the speed of the molecules and the $y$-axis represents the fraction or number of molecules.At lower temperatures,the molecules have lower average kinetic energy,so the peak of the distribution is shifted towards lower speeds and the curve is narrower and taller.As the temperature increases,the average kinetic energy of the molecules increases,causing the peak of the distribution to shift towards higher speeds,and the curve becomes broader and flatter.Therefore,for temperatures $T_1 < T_2 < T_3$,the correct plot shows the peak shifting to the right as temperature increases,which corresponds to the graph in option $A$.

The correct plot of the Maxwell-Boltzmann distribution at different temperatures $(T)$ is:
