Reasoning:
(a) The term dimension is used to refer to the physical natureof a quantity, and the type of unit used to specify it. Quantitiesof the same dimensions mean that only the physical quantity usedremains the same.
According to the system of units, the used physical quantity canhave different units, such as MKS and CGS. Hence, for one quantity,there will be one dimension, but there will be multitudes of unitsthat will be used for measuring that quantity.
For example, consider the physical quantity LENGTH. It has thedimensions L. The length will have the same measurement, itbut can be expressed in different units. So, if the length is 5meters, we can say that the length is.The magnitude remains the same, but it is expressed in differentunit systems. Thus, we see that the dimension L remains thesame, even if we express it in different units.
Yes, quantities that have the same dimensions can havedifferent units.

(b) Units give the magnitude or measurement of a variety ofquantities that are relative to any standard set. Two quantitiesthat have the same units (MKS or CGS) cannot be different inphysical nature.
For example, consider the physical quantity LENGTH to bemeasured using the MKS system. So, its units will only be inmeters. Now, consider that we need to measure the DISTANCE coveredby a person from point A to B. Then, in the MKSsystem, the distance will be measured in meters only. So, the unitis meters. This means that the physical nature of the twoquantities remains the same. So, they cannot have differentdimensions.
No, quantities that have the same units cannot havedifferent dimensions because the physical quantity that is measuredthroughout that unit is the same.
