Kinetic Energy of a body is given by,
[tex]\begin{gathered} K.E.=\frac{1}{2}mv^2 \\ Where, \\ K.E.=Kinetic\text{ }Energy \\ m=Mass \\ v=Velocity\text{ }or\text{ }Speed \end{gathered}[/tex]So,
[tex]\begin{gathered} Here; \\ m=0.15kg;\text{ }v=40\text{ }m\text{/s} \\ So, \\ K.E.=\frac{1}{2}\times0.15\times(40)^2=120J \end{gathered}[/tex]So, the kinetic energy of baseball is 120 Joule.
So 1st option is correct option.
