Option (b)Because all the options except (b) contain mass,length and time directly or indirectly.option (b) does not contain `mass` which is a fundamental quantity.

Dear student,
 
For the units to serve as fundamental quantities, the provided quantities must be able to express all other fundamental units using them. But due to distinction in units, for e.g. mass being a measure of substance, length being a dimension, time being an observed phenomenon, they are entirely different and cannot be represented by one another.
Coming back to our question. In 3 of the given options, the basic units like time, mass and length are present in atleast one entity. But in option b) mass is missing and neither of the three given entity can be used to obtain it.
Hence, option b) is correct.
 
Hope it helps.
Thanks and regards,
Kushagra
