Option 1 : ML^{2}T^{-2}

__CONCEPT:__

- The expression showing the powers to which the fundamental units are to be raised to obtain one unit of a derived quantity is called the dimensional formula of that quantity.
- If Q is the unit of a derived quantity represented by Q= M
^{a}L^{b}T^{c, }then M^{a}L^{b}T^{c}is called dimensional formula and the exponents a, b ad c are called the dimensions

__EXPLANATION:__

W = Force × Distance

= Mass × Acceleration × distance

- Dimension of work = [M} × [LT
^{-2}] × [L]

= [ML^{2}T^{-2}]

- option 1 is the correct answer.
