The dimensional constant among the options given is C Planck’s constant.

Here's why:

A. Force is not a dimensional constant. It is a vector quantity with dimensions [MLT^-2] in the MKS system.

B. Momentum is also not a dimensional constant. It is a vector quantity with dimensions [MLT^-1] in the MKS system.

C. Planck’s constant (h) is a dimensional constant. It has dimensions of energy multiplied by time, which are [ML^2T^-1] in the MKS system.

D. Specific gravity is a dimensionless quantity. It is the ratio of the density of a substance to the density of a reference substance. As it is a ratio, it has no dimensions.
