Answer 2

[ML−3T2K−1]D. [M−1L−2T3K] Hint: In order to solve this question first we will define the term thermal resistance, further then we will write its formula and with the help of this formula we will evaluate the required answer by manipulating the formula and using the dimensional formula for other units.
