Match list - I with list - II and select the correct answer :

 Spring constant $M^1\,L^2\,T^{-2}$ Pascal $M^0\,L^0\,T^{-1}$ Hertz $M^1\,L^0\,T^{-2}$ Joule $M^1\,L^{-1}\,T^{-2}$

2,7,9,12

SOLUTION
Spring constant : $k =\dfrac{F}{x} = \dfrac{MLT^{-2}}{L}=M^1L^0T^{-2}$, Hence A->3
Pascal: $P = \dfrac{F}{A} = \dfrac{MLT^{-2}}{L^2} = M^1L^{-1}T^{-2}$ , Hence B->4
Hertz: $f =\dfrac{1}{T} = M^0L^0T^{-1}$, Hence, C->2
Joule: $W= F \times distance = M^1L^2T^{-2}$, Hence D->1
