Option C is the correct answer.
According to the International System of Units or SI, there are some differences between unit symbol and dimension symbol.
The dimension symbols are strictly used for the SI base units such as metre, kilogram, second, ampere, Kelvin and candela.
These symbols are not derived from the Newton and Joules law.
