L = mvr. m = 3kg, v = 4.2m/s, r = 0.7m. L = 3×4.2×0.7 = 8.82kg m2/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 8.82 kg m²/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.

L = mvr. m = 3kg, v = 4m/s, r = 0.6m. L = 3×4×0.6 = 7.2kg m2/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 7.2 kg m²/s. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.

L = mvr. m = 4kg, v = 2m/s, r = 0.25m. L = 4×2×0.25 = 2kg m2/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 2 kg m²/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
