For an object in projectile motion, which component of acceleration is zero?
Projectile motion splits into horizontal uniform and vertical accelerated motion per NCERT Chapter 4. Range R=u²sin2θ/g and max height H=u²sin²θ/2g. Using given u, θ, g, calculation yields Horizontal component. Hence option B satisfies projectile formulas.
