(B) The equation of the trajectory of a projectile is given by: $y = x \tan \theta \left( 1 - \frac{x}{R} \right)$,where $R$ is the horizontal range.Given: $\theta = 45^o$,$x = 4 \, m$ (distance of the wall from the projection point),and the total range $R = 4 \, m + 6 \, m = 10 \, m$.Substituting these values into the trajectory equation:$y = 4 \tan(45^o) \left( 1 - \frac{4}{10} \right)$$y = 4 \times 1 \times (1 - 0.4)$$y = 4 \times 0.6 = 2.4 \, m$.Thus,the height of the wall is $2.4 \, m$.
