Physics

The physical quantity which has the dimensional formula ${ M }^{ 1 }{ T }^{ -3 }$ is:

solar constant

SOLUTION
Surface tension $\displaystyle \rightarrow \frac{F}{l}=\frac{MLT^{-2}}{L}=MT^{-2}$

Solar constant $=MT^{-3}$

Density $=\dfrac{Mass}{Vol}=ML^{-3}$
Compressibillity $=\dfrac{1}{Bulk \ Modulus}=\dfrac{\dfrac{dv}{v}}{dp}=\dfrac{L^{3}/L^{3}}{ML^{-1}T^{-2}}=M^{-1}L^{1}T^{2}$

Hence, option B is correct.
