(b) Dimensional homogeneity

(c) Dimensional variable

(d) Dimensional analysis

This question was addressed to me by my college professor while I was bunking the class.

Answer 1

Right option is (d) Dimensional analysis

The explanation: The study of variables corelated to their physical phenomena and studying them analytically to solve problems refers to Dimensional analysis. If the equation expresses a proper relationship between the both, then dimensional homogeneity is obtained and the varying quantities are called dimensional variables, whereas the values normally held constant, are called dimensional constants.
