Answer: D. [tex]102\ m^2[/tex]

Step-by-step explanation:

Given : The surface area of a triangular pyramid is [tex]408 m^2[/tex].

We know that the total number faces in a triangular pyramid =4

If all the faces of the pyramid are congruent, then the area of one face of this pyramid will be :_

[tex]408\div 4=102\ m^2[/tex]

Hence, the area of one face of this pyramid = [tex]102\ m^2[/tex]
