Expert Answer:

In a triangular prism, the bases are triangles and the lateral faces are parallelograms.
 
Thus it can be both rectangles and parallelograms.
 
So, option (c) is correct.
 
If the faces are rectangles, then we call it as right triangular prism.
 
 
Observe the following figure.
 
It is clear that the faces of the above figure are rectangles and hence it is right triangular prism.
