Velocity (v) and acceleration (a) in two systems of units 1 and 2 are related as v₂ = n/m² v₁ and a₂ = a₁/mn respectively. Here m and n are constants. The relations for distance and time in two systems respectively are : A) n³/m³ L₁=L₂ and n²m T₁=T₂ B) L₁= n⁴/m² L₂ and T₁= n²/m T₂ C) L₁= n²/m L₂ and T₁= n⁴/m² T₂ D) n²/m L₁=L₂ and n⁴/m² T₁=T₂
