Answer: A. B = L/T
Step-by-step explanation:
Since the relationship between displacement and time is related by the equation x =Bt,
The displacement is measured in meter which specifies the length (L). Time (T) is measured in seconds. To get the dimension of B, we need to make B the subject of the formula first that is B = x/t
Writing B in terms of its dimension will give us B = L/T
